Unable to login Admin CP

Post by old fart » Wed Dec 07, 2022 11:24 pm

My Joomla version is current.
Updated PHP version to 8

See attached image (below) of the message now displaying on the Admin login page where the login normally is.

Any suggestions as to why this may have happened, and, how do I fix it so I can login in?

Thanks in advance.

PS I am only a learner so please be gentle on me with all the techie do this and do that. I will do my best to follow instructions. Cheers.

These types of errors come from third party extensions that are not compatible with PHP 8. In this case it is most likely a plugin.

If you are unable to login to the back end because of the error, use phpMyAdmin in the cPanel or a similar page provided by your host to edit the extensions table in the database. Locate all third party plugins and change the column 'enabled' from 1 to 0, one at a time, go to the back end and check if the message has disappeared.

Alternatively, edit the file configuration.php in the main Joomla folder and set the error reporting option to the highest value and turn on the Debug option so the error message will have more details that identify the script where the message comes from:

Code: Select all

	public $debug = true;	
	public $error_reporting = 'maximum';
