Sticky [Resolved] Fatal error: Call to a member function authorisedLevels() on a non-object in /administrator/components/com_kunena/libraries/integration/joomla16/access.php on line 57

Did you also revert the hack? I suggest you re-install Kunena 1.7.2 (you won't lose any data) just to be doubly sure and, if necessary, restore the Kunena Forum Configuration back to its original default values.

APC - yes, we have problems with that one, too; requires a thorough understanding of caching to get APC to work properly and I leave those kinds of things to the experts. I just use straight, out-of-the-box, vanilla-flavoured Joomla (and the same for Kunena) and I turn off caching altogether. I hate to sound boastful but I rarely ever have a problem.

Thank you for your reply,

I agree APC was not playing nicely with joomla hence the switch to Xcache that really speeds things up (needed for my site with over 7k users), I have also tested without xcache (removed from php.ini AND joomla) after a reboot and had the same errors)

yes I have removed the hack and I still get the errors.
I uninstalled kunena+modules completely and reinstalled a fresh one with
Sample Data, so far so good no errors while browsing...I can't figure out why but hey, as long as it works

Will work on importing my phpbb3 forum this afternoon and report back. fingers crossed.

All sorted, the forum import worked and the errors are gone.
I will never find out what was wrong, my advice for the users
who have this issue: a clean re-install works.

Thank you again for your help.

Yesterday all was good with my website... I had not added anything new in last 24 hours... this morning I went online and the everything was good until I tried to get into my Kunena based forum... and I got this message...
