Joomla 4 Crashes After changing Global Configuration Information

[linuxcourseware]

If you are submitting an issue for the Joomla! CMS, please submit it at https://github.com/joomla/joomla-cms/issues/new instead. You may remove this line from the issue template.

Steps to reproduce the issue

Install Joomla4 via upgrade from 3.10 PHP 8 or 7.4 (installing on a subdomain)
Go to Global Configuration and make any change. My first experience was when I tried to change the editor to JCE. After several attempts, I tried to make and save a change (Hide Author Meta Data) to Global Configuration without any extensions (e.g., JCE, Akeeba...) and save the config file. Once the save button was pressed a login screen appeared and did not allow me to logon. I tried to change the password via PHPmyadmin, but that did not work.

Expected result

Save the file without exiting

Actual result

Logs out and cannot login. I can load extensions and work with extensions successfully, but if I touch Global Configuration after the install I lose the system

System information (as much as possible)

Joomla 4 Upgraded from 3.10 tried with both PHP 8 and then 7.4
I have it installed on a subdomain.

Additional comments

Could someone tell me how to fix this. I have been trying to figure this out for two days.

@b2z thats exactly what he did...

There is a similar issue where 3.10 is not reading the configuration file properly if permissions are 444.
To recreate this set error_reporting to developement and php.ini to display_errors: off
system->info will read that its on, even though the global config show that its off.
change perms to 644 and it will read correctly.

This project is not for Joomla CMS, but for Joomla Tracker Application.
