Call to undefined method Joomla\CMS\Application\AdministratorApplication::isSite()

Post by netx84 » Sun Oct 17, 2021 6:57 pm

Hello everyone,
after upgrading from joomla 3.10.2 to 4.0.3, I have some errors that are preventing me from accessing the backend of the site. The website is also not working :( This is a very important issue for me because if it fails to migrate the site I will have to make it from scratch.

Please help me :(

Please note that the offending plugin was identified before you did the upgrade and you were advised to disable it
