I get this error message when trying to login to my site using Tapatalk (I'm using JFusion for phpBB). I have had no problem with this before, and I have no clue what my last changes was that stopped it from working, as I have done so much since last time. Obviously it's somehow related to K2.

Fatal error: Class 'K2Table' not found in /path/to/administrator/components/com_k2/tables/k2user.php on line 14

Not only when using Tapatalk. I believe it's related to JFusion, phpBB and K2 somehow.

Disabling K2 user plugin fixed that it seems.,
