Dear Akeeba,

I'm attempting to migrate this website from Joomla 3.10.12 to the current Joomla 4 release. In the prep stages I was instructed to install your Magic Eraser extension and right after this install I got this error (screen shot attached).

An error has occurred.
0 Class 'F0FInput' not found

I'm unable to navigate past this error in the admin portal. What do I need to do to get past this error screen?

regards,

Ed H.

You have an extension last updated before March 2015 —that's over 8 years ago— which is using an ancient version of FOF 2 which we discontinued in June 2016. Since you've already used Magic Eraser it's some third party extension using FOF 2 (Magic Eraser removes all Akeeba extensions doing that, unless there is an error in Joomla or PHP itself).

Edit your configuration.php file, set $error_reporting = 'development' and retry loading the page. You should get a more detailed error message, showing which file this comes from. Send us this error message to help you further.

Nic,

 

Thanks for your assistance and sorry for ringing you bell... the problem (as you noted) was being generated by another extension. As such, I contacted that developer and they provided an updated release that not only fixed this issue but is also Joomla 4 Ready. Thanks again!
