Hello, when i disable K2 extension completely, main page of the backend crash:



But when i check other pages, they work ok. Also K2 didn't dissapeared from components menu:



Frontend works correctly.

What happens, and how to fix it? Previously i removed K2 completely and i had to reinstall website from backup.



Kind Regards

You cannot simply disable the plugin, you have to unistall the extension itself, there are a lot dependencies.

Also I think you are using an outdated version of K2.
