you can check out the error log and get more information on what is causing the error. If you have an administrator gui provided to you by your host, that will be a good place to check. Here is an example video for cPanel (you will want to check with your host for how to access this report on your specific admin. interface):

I am also getting 500 Internal server error.
My Problem

Try checking the server error. In my case I used

cd /var/log

Then I used sudo cat apache2/access.log
(I was not able to cd into the apache2 directory directly, so this workaround)

also try sudo cat apache2/error.log if it helps.

In my case, it was due to a Japanese space (Zenkaku space) in my PHP file.

For PHP, it shows errors to the client side or logs errors to a file depends on how you configure the php.ini file. Either way, I got nothing from PHP when there is a Japanese space in the myfile.php

My production web_server had the xdebugger setting disabled in it’s php settings.
I reenabled the xdebugger and the server 500 error was replaced by the php script error in php page.

Are the websites in your server giving ‘500 internal server error’ all of a sudden? In our role as Outsourced server support specialists for web hosts, this is one commonly encountered errors in Apache web server.

A PHP upgrade, Apache recompilation, permission or ownership changes, anything can trigger a 500 error in a website. The impact of the error can vary based on the cause that triggered it.

See how we help web hosting companies

Today, we’ll discuss the probable causes for ‘500 internal server error’ in Apache and how to resolve them.

What causes ‘500 internal server error’ in Apache?

‘500 internal server error’ is a very broad error, and to pin-point the actual cause of the issue, it is very vital to observe the Apache/PHP error logs and to detect the recent changes made in the server.

With our years of experience handling web servers for a wide range of web hosting companies, we’ve come across several causes that can trigger this error, such as:

  • A PHP upgrade or Apache recompilation that went wrong – Due to compatibility issues or unsupported modules in Apache/PHP, the websites can throw 500 errors.
  • Errors in the format or content of PHP or CGI scripts – A code error, unsupported format or wrong path to the binary, can generate errors in the scripts.
  • Settings in .htaccess or other config files that are not supported – For instance, servers that run SuPHP do not support php_flag or php_value directives in .htaccess files.
  • Server or file system restrictions such as log file size, SELinux restrictions or time out settings for executing a script.
  • Errors related to the PHP config file – Any unsupported or invalid setting in php.ini can lead to 500 errors.
  • Incorrect permissions and ownership for the files – In SuPHP, files and folders should be under user ownership, folders should have 755 permissions, non-scripts files need 644, PHP Scripts require 600 and 755 is needed for CGI and shell scripts.
  • A web server or PHP module that is not working fine – A corrupt php.ini file, a module that is no longer supported, etc. can also lead to 500 internal server errors in Apache.

How to resolve ‘500 internal server error’ in Apache

When we come across customers who complain about 500 errors, we first check whether the error affects just one site or every site in the server. Depending on the impact of the error, we debug further.

If only one domain it affected, it can be pin-pointed to the specific script error or permission issues. If multiple domains show 500 error, it could be due to some server wide setting change or update.

From the Apache error logs, we detect the script or the module that is the culprit. We follow a systematic debugging approach, which helps us resolve the error in no time.

As improperly planned Apache updates or recompilation can cause server wide errors or PHP module to malfunction, we take proper caution and do adequate testing to avoid a web site downtime for our customers.

[ Use your time to build your business. We’ll take care of your servers. Hire our server support experts to maintain your servers secure and stable 24/7 . ]

At Bobcares, our 24/7 server specialists constantly monitor all the services in the server and proactively audit the server for any errors or corruption in them.

With our systematic debugging approach for service or other software errors, we have been able to provide an exciting support experience to the customers.

Many times Apache gives 500 Internal Server Error due to various reasons. In the article, we will look at what is 500 internal server error, why do you get this error message and how to fix 500 Internal Server Error in Apache localhost, CPanel other systems like Ubuntu, CentOS, Windows.

Apache gives 500 Internal Server Error when there is a server-side error that prevents Apache from processing a request and returning a proper response. This can be due to various reasons such as faulty code, inadequate file permissions, missing files referenced in code, etc. There are multiple ways to fix 500 internal server error in Apache.

How to Fix 500 Internal Server Error in Apache

Here are the steps to fix 500 internal server error in Apache on localhost, CPanel, PHP, Ubuntu, and other systems.

1. Hard Refresh the Page

The simplest way to fix 500 internal server error in Apache is to simply refresh the page. Sometimes you may be requesting a page when the server is being restarted. In such cases, you will get 500 internal error.

Sometimes, the server may be overloaded with requests and doesn’t have resources to process your request.

In both these cases, you can do a hard refresh to force the browser to connect to server and download the latest website content. You can do this by pressing

  • Windows: Ctrl + F5
  • Mac: Apple + R or Cmd + R
  • Linux: F5

2. Examine Server Logs

Many times, you get 500 internal server error only for one page or a few pages but not all pages on your website. So it is important to check your server log to find the requests causing this issue.

Every server log records the requested URL along with the returned response. Among the most recent requests, look for the ones that have returned 500 response code.

This will tell which script is causing the issue. Once you have identified the script, open your browser and request this page again to confirm that it is indeed raising the error in server log.

3. Examine your script

Next, check if your script is working properly.

Is your script in the right place? Have you named it correctly? Is your URL mapping/routing referencing the right script?

If your script refers any file, then are the file paths correct? If they refer any function/program, have you referenced them correctly ?

4. Check File/Folder Permissions

Did you modify any file/folder permission recently? Did you create a new file/folder in your code?

If so then you might be seeing 500 internal server error due to wrong file/folder permissions. Typically, files should have 644 user permission while folders should have 755 permission. You can use FileZilla (Windows) or CHMOD (Linux) to change file permissions.

Look at the permissions of other files/folders in your code and update the permission for your file/folder accordingly.

5. Check .htaccess file

If you have set up URL rewrites or URL redirection, then you may have used .htaccess file. Make sure you have setup mod_rewrite correctly.

Also use a third-party tool to check URL rewrite syntax, and ensure they are correct.

6. Increase Script Timeout

If your Apache server depends on another external script/function to process a request and it times out, then Apache will return 500 Internal Server error.

So increase the timeout values of those external scripts so that they maintain the connection and return a proper response.

Hopefully, the above tips will help you fix 500 internal server error in Apache.

Создание и настройка своего сайта является приятным моментом для вебмастеров. Но иногда они могут сталкиваться с ошибкой «Internal Server Error – The server encountered an internal error or misconfiguration and was unable to complete your request».

  5. Как создать черный список в .htaccess

Причины ошибки

Данная ошибка в переводе звучит так: внутренняя ошибка сервера. Система обнаружила внутренний сбой или неверные настройки и не смогла сформировать запрос. Это значит, что какие-то настройки загруженного движка или других файлов неверна, из-за чего и происходит ошибка. Одной из распространенных причин данной проблемы сервера являются ошибки файла .htaccess. Это дополнительный файл для предоставления определенных команд для серверов, в частности Apache.

Картинка файла .htacess в перечне

Многим вебмастерам удается исправить ошибку «Internal Server Error», исследовав внимательной этот файл. В нем может быть указан неверный домен или вовсе запрещен доступ к сайту. Файл .htaccess дает возможность: изменять настройки для всего сайта, защищать определенные каталоги паролем, создавать черные списки из URL, разрешать доступ только избранным сайтам и многое другое.

Где в панели администратора найти .htaccess

Для того, чтобы отредактировать файл, его нужно найти в вашей админ-панели. На хостинге, который имеет cPanel и в движке WordPress этот файл расположен в каталоге public_html.

  1. Выберите каталог, и найдите файл.
  2. После этого в контекстном меню выберите «Редактировать». Он может находится в скрытых файлах.
  3. Вам нужно их отобразить, найдите кнопку «Настройки» и измените пункт «Отобразить скрытые файлы».
  4. Если его вообще нет, вы можете создать его самостоятельно. Нажмите в файловом менеджере кнопку «Файл» вверху и создайте файл .htaccess.

Рекомендую ознакомиться: На этой странице произошла ошибка сценария – Решение.

Устранение ошибки сервера

При внимательном изучении файла .htaccess можно определить из-за чего появляется сообщение Internal Server Error. Иногда пользователям удается определить наверняка, что ошибка в файле .htaccess. Для этого нужно удалить все содержимое из него и сохранить в другой текстовый файл, чтобы не потерять. После этого нужно открыть сайт, если ошибки не возникает, значит причина в файле.

Для начала попробуем отыскать параметры файла, которые могут вызывать эту ошибку. Найдите в своем .htaccess такие строки:

  • Option,
  • php_flag,
  • php_value.

Их необходимо закомментировать. Для этого в начале строки, которая содержит эти параметры нужно поставить знак решетки — #. Закомментированная строка будет выглядеть так: # php_value. Между решеткой и следующим символом необходимо ставить пробел. Для WordPress может понадобиться еще закомментировать следующие параметры: SecFilterEngine Off и SecFilterScanPOST Off.

Возможно в вашем файле нужно установить кодировку, попробуйте закомментировать следующую строку: AddDefaultCharset WINDOWS-1251. Попробуйте изменить на UTF-8. Также нужно найти (если есть) в файле строку # RewriteBase / и убрать из него символ решетки. Просмотрите ссылки в тексте .htaccess, возможно они неверны.

Интересно: ERR_CACHE_MISS — как исправить ошибку?

Другие способы устранить The server encountered an internal error

Найдите в своем файле .htaccess строку AllowOverride All. Если здесь стоит решетка (#), уберите её.

  • Необходимо также проверить, что для домена существует следующая запись VirtualHost. В качестве примера можно посмотреть на скриншоте как выглядит запись; Запись VirtualHost
    Запись VirtualHost в файле .htaccess
  • Убедитесь, что конфигурационный файл содержит хостнейм сервера (обычно указывается в виде домена или IP-адреса);
  • Попробуйте запретить доступ всем входящий IP-адресам с целью проверить работу .htaccess — Deny from all.

Как создать черный список в .htaccess

Вы можете создать свой список из IP-адресов, которые не смогут попасть на ваш сайт. Для этого нужно найти файл .htaccess и отредактировать его. Следующий код, который будет блокировать адреса нужно вводить с новой строки.

  1. Можно в начале кода поставить знак комментария #, чтобы пояснить для себя на будущее для чего он. Например, # Черный список для хамов;
  2. Первой строкой разрешаем посещение для всех адресов — allow from all;
  3. Следующий код будет блокировать указанный адрес — deny from86.164.01;
  4. Добавляем еще один IP-адрес — deny from484.015.44.

Этот список может продолжаться бесконечно. Если вы не знаете, какой адрес у назойливых комментаторов, их можно подсмотреть в логах вашего сервера. В разных движках есть свои методы определения адресов. Это могут делать и сторонние скрипты PHP. Универсальным способ для всех движков определить IP-адрес — найти соответствующий раздел «Логи сервера». На платформе cPanel — это раздел «Посетители».

It’s probably not your problem to fix.

Internal Server Error
(Image: canva.com)

An «Internal Server Error» happens within the web server attempting to show you a web page. It’s usually a server-side problem out of your control.

I’m trying to download software from a specific site. No matter what I try to download, I get this error message:

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator webmaster@******.com and inform them of the time the error occurred and anything you might have done that may have caused the error. More information about this error may be available in the server error log.
Additionally, a 500 Internal Server Error was encountered while trying to use an ErrorDocument to handle the request.

How is this resolved?

I’m very familiar with this error. I see it all the time when setting up or making changes to websites.

The good news? It’s not your fault.

The bad news? There’s probably nothing you can do.

TL;DR:

  • It’s not really your problem, and there’s likely nothing you can do.
  • Make sure the URL you’re going to is exactly correct.
  • Links in email are sometimes broken by line wrapping.
  • Treating it like a browser problem can help.
  • If you’re the webmaster, there are probably some clues on your server.

It’s the server’s problem

An internal server error is an error on the web server you’re trying to access. That server is misconfigured in some way that prevents it from responding properly to what you’re asking it to do.

Think of it like the web’s version of a blue screen. :-) Something went so wrong on the server that it couldn’t even tell you what the problem was.

Internal Server Error

Aside from informing the site owner (who may or may not be at the webmaster’s email address included in the error message), there’s probably nothing you can do to resolve this problem. That’s because it’s not your problem.

The person who is responsible for the website needs to fix it.

It’s still the server’s fault, but…

Even though it’s the server’s fault for not handling something properly, there are scenarios where you might have inadvertently caused this. For example, errors in URLs can cause it.

One scenario: you saw a link in an email or webpage, and rather than clicking on it, you copied and pasted the link in a web browser. If you accidentally didn’t select the entire link and left off a few important characters, you might see this message.

Similarly, if you’re typing in a URL from a book or other source, and don’t type it in exactly, you might see this message.

To be clear, the server should be able to handle whatever you did cleanly and report errors in some useful way. If the server doesn’t, and you get an Internal Server Error message, it’s still the server’s fault.

There are some straws to grasp at

An internal server error happens when the server encounters a situation it doesn’t know how to handle.  Occasionally, your browser can be the source of these kinds of errors. You can try these steps to see if they’ll help:

  • Clear the browser cache
  • Clear cookies
  • Refresh the page (F5)
  • Try a different browser

While it’s more than likely these won’t work, there’s always a chance they might, and they are simple to try.

If you’re the webmaster…

What if you’re the webmaster?

Nine times out of 10, this error results from one of two common errors:

  • An error in a CGI script caused it to fail or output an error message before it started producing valid HTML. It happens to me all the time if I have a syntax error in one of my Perl CGI scripts.
  • A permissions issue occurred when attempting to access a CGI script. Depending on how your web server is configured, it’s not enough for the script to have “execute” permission; it must also be owned by the correct user and belong to the correct group. I can’t tell you what that should be, because it varies widely from server to server (and even from site to site on the same server). My best recommendation is to look at the attributes of a script that is working and copy that.

The format of the error described here is common for Apache web servers. That means we can also look for common error logs. Once again, the location of these logs varies a great deal based on specific web server configuration.

  • access_log is the log of successful accesses. On a shared or virtual hosting server, there may be many of these: one per website, often with site-specific names or in site-specific locations on the server.
  • error_log is the log of errors. On some hosts, there is an error log per site. On others, each site has its own access_log, but there may only be a single error_log for the system.
  • suexec_log is the log most people forget. It deals with the permissions used to execute CGI and other scripts. When a CGI fails to execute because its ownership is wrong, the generic internal server error shows in the error log, but a more specific error detailing the permissions involved appears in this log.

Additionally?

The message “Additionally, a 500 Internal Server Error was encountered while trying to use an ErrorDocument…” indicates a second configuration error on the server.

When the web server encounters an error of any sort, the page it displays to report the error is just another .html file stored on the server. This error means that trying to display the error page for the first error (the internal server error) actually generated a second error (also an internal server error, in your case).

At that point, the server just gave up.
