Solved Installed but error with category and Jomsocial plugin

Ok, so i am finally getting my head around Kunena. Great forum software, but i have come across an issue.

When i create a category, it works fine. After enabling the Jomsocial plugin and then create a new category, I get this error:An error has occurred.

0 Cannot set the query type to "update" as the query type is already set to "select". You should either call the `clear()` method to reset the type or create a new query object.

Can anyone tell me why this is and what I can do to fix or rectify this? I would prefer to have the jomsocial plugin enabled.

Clear cache?

Great idea, but that doesnt work with the error. Error is still showing up.

Please create a Configuration Report

Sorry but don;t need to now as the fault was with theKunena - JomSocial Integration plugin. I disabled the Enable Access Control and the forum all works fine now.
