Administrator Login Error

[java009]

I am using Windows Server 2012 R2 with IIS version 8.5. I successfully Installed PHP7.2, MySQL5.7 and phpmyadmin. I already setup Joomla, and when I go to the Administrator/index.php and then login, I got 500 Internal Server error. Then I enable error notification log on IIS and got the following login error on Joomla Administrator login:

PHP Warning: session_set_save_handler(): Cannot change save handler when session is active in C:\inetpub\wwwroot\libraries\joomla\session\storage.php on line 106
PHP Warning: session_set_cookie_params(): Cannot change session cookie parameters when session is active in C:\inetpub\wwwroot\libraries\src\Session\Session.php on line 807

Can someone please help me how to fix this problem? Thank You so much.

From my [very quick] search on Google, this looks like a issue arising from the version of PHP you've installed. As a test, can you try a different version of PHP (e.g. PHP 7.1.something)?

I tried to use different version of PHP still got the same error.

I suggest that you use the Forum Post Assistant; perhaps there is something in that report that may help someone to advise you on what you should do next.

Try to change your session handler in configuration.php.
public $session_handler = 'database';
either one try to play around
public $session_handler = 'none';

I'm seeing the same two PHP Warning messages in administrator/error.log for both of my sites and I've got the session handler set to Database for both sites. Both sites are running Joomla 3.8.5 and the PHP version is 7.2. Webserver is Apache. I tried switching to PHP 7.1 and the file reappears as soon as I log into the site back end.

@basherz: I think your question relates to the topic insofar as you have an "error" somewhere. My question to you is simple: are you actually able to login to your administrator backend?

I'm seeing the same two PHP Warning messages in administrator/error.log ...

Warnings are not the same as errors that prevent people from logging in or using their sites. What are the details of the PHP warning messages that you see in the error log file?

I tried switching to PHP 7.1 and the file reappears as soon as I log into the site back end.

What "file" is "reappearing" and where is it "reappearing"?

I didn't say they were errors and I did say that they appeared in the file administrator/error.log after logging into the site back end. I was replying to the original post because I am seeing the following two warning messages in the above file. When I delete the file, it reappears when I log into the site back end, which means these warnings occur every time a back end login succeeds.

Code: Select all

PHP Warning: session_set_save_handler(): Cannot change save handler when session is active in C:\inetpub\wwwroot\libraries\joomla\session\storage.php on line 106
PHP Warning: session_set_cookie_params(): Cannot change session cookie parameters when session is active in C:\inetpub\wwwroot\libraries\src\Session\Session.php on line 807

The original poster noticed this back in December 2017 but did not state which J! version, and only tried PHP 7.2. I reported J! 3.8.5 and that the file reappears even when using PHP 7.1. Sure felt like I was providing more information about the issue, which is an OBSERVATION not an ERROR. This is called community feedback. It's supposed to help the developers. I am not looking for assistance.
