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

Post by ozwest » Sat Sep 25, 2021 4:16 pm

I have just upgraded my site https://seelenort.com to Joomla 4.

I was logged into the new administrator and found the error message saying that Cache Cleaner plugin was disabled because it needs to be upgraded.

I see the error mentioned in the title and I don't seem to be able to get access to anything.

Also the site shows a Page Not Found.

Any ideas on what to do? Thank you.
