Administration Joomla! 4.x • Re: Cannot navigate to /administrator page - An error has occurred

Welcome to the Joomla forum!

The FPA shows that there are a couple of issues, not related to the current problem, but issues in any case.

Max. Input Time: -1 | Max. Execution Time: 50000 | Memory Limit: -1
Those are unusual values. Usually PHP is configured with 60, 30, 256M, as an example.

A number of folders associated with the JEvents extension have elevated permissions 777, which is a security risk. All folders should have the permissions 755.

About the issue, "Could not instantiate mail function". Has the Joomla mail configuration perhaps been modified, or have you or your host changed something relating to the mail server used by the website?

Did one of the installed Joomla plugins previously send an email to the administrators when members of the Super Users user group logged in?

Now the first task at hand is to restore access to the backend. Write-enable and then edit the file configuration.php and make the following changes:

Code:

public $debug = true;public $error_reporting = 'maximum';public $log_everything = 1;
Access the backend and copy and paste the messages into your reply. The error message is followed by the PHP call stack, around a dozen lines that are important, as long as the PHP extension Xdebug is enabled in PHP.

Once the root cause is identified, the plugin can be disabled by editing the database table _extensions. The row with the details of the plugin has a column 'enabled'. Change the value from 1 to 0.

Please note that the developer of the third party extension Mailster released an updated version yesterday.
