An error was encountered the action you have requested is not allowed

I enabled the csrf_protection option in codeigniter’s config file, and used form_open() function to create my forms. But when I submit the form, this error occurs:

The action you have requested is not allowed.

I have done the answers like this topic (that is most related to my question): question

but they didn’t work and The problem still remains.

my config.php:

У меня есть форма, использующая скобки для кодировки

echo form_open('signup'); echo form_close(); 

и когда я отправлю его, я получаю следующую ошибку

• Уникальный формальный токен отключает многозадачность для пользователя
• Данные формы Laravel не сохраняются в графике DB neo4j
• Lavavel 5.2.36 МетодNotAllowedHttpException в строке RouteCollection.php 218:
• Codeigniter CSRF действителен только для одного запроса ajax

 An Error Was Encountered The action you have requested is not allowed. 

НЕ always но часто …

даже если скрытое входное поле существует внутри формы:

 <div style="display:none"> <input type="hidden" value="token name is here" name="csrf_token_name"> </div> 

это также происходит в аналогичной форме (signin)

EDIT: html, сгенерированный через форму

 <form accept-charset="utf-8" method="post" action="http://www.example.com/signup"> <div style="display:none"> <input type="hidden" value="93565fb5855d31af3d46bd655b11a4a6" name="csrf_token_name"> </div> <input id="username" type="text" placeholder="Username" maxlength="20" value="" name="username"> <input id="email" type="text" placeholder="Email" value="" name="email"> <input id="password" type="password" placeholder="Password" value="" name="password"> <input id="submit" type="submit" value="Sign up" name="submit"> </form>

Issue / Question / Bug

Before submitting an issue please make sure you tick (add an x between the square brackets with no spaces) the following check boxes:

• I’m reporting an issue of an unmodified OSPOS installation
• I checked open and closed issues database and no similar issue was already discussed (please make sure you searched!)
• I read the README, WHATS_NEW and UPGRADE
• I read the FAQ (https://github.com/jekkos/opensourcepos#faq) for any known install and/or upgrade gotchas (in specific PHP has php-gd, php-intl, sockets and etc. installed)
• I read the wiki
• [?] I ran any database upgrade scripts (e.g. database/2.4_to_3.0.sql), and migrating function
• I’m aware the latest master could be a development version and therefore not stable
• I know the version of OSPOS and git commit hash (check the footer of your OSPOS), the name and version of OS, Web server, PHP and MySQL and will add them to my issue report

Installation information

• OSPOS version is: 3.0.2
• OSPOS git commit hash is: 4f5ad57
• PHP version is: (e.g. 5.5, 5.6, 7.0, 7.1) 5.6

• OS and version is: (e.g. CentOS 6.9, Ubuntu 16.4, Windows 10) Raspbian 8 Jessie
• WebServer is: (e.g. Apache 2.2, Apache 2.4, Nginx 1.12, Nginx 1.13) 2.4.10
• (If applicable) Installation package for the LAMP/LEMP stack is: (e.g. WAMP, XAMPP)

Expected behaviour

Go to home page after logging in.

Actual behaviour

An Error Was Encountered
The action you have requested is not allowed.

Steps to reproduce the issue

I have a client rpi that I vpn, from remote location, to the server rpi. I let the client sit idle for a few hours then I get this error. If I «go back» I then can log in and get directed to home page and use as expected. Refreshing does not help.

GLPI is connected to the database with root user.
I checked the permissions on the folder and they are ok.

I think it’s something with CSRF token.
