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

I have asked for help from my colleagues.

I do not know how the conditions arise that cause the 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

As far as I know, this issue was resolved a long time ago. I do not know why the problems persist in your case.

Thanks for forwarding this to your colleagues. I deeply hope someone has an idea because the Kunena forum plays a huge role on our site and it is important that its visible for guests without issues. Kunena was the last 4-5 years so nice to me and I won't (cannot) use any other forum component.

If you guys need more information from me or my system please let me know and I'll be here for you asap.

I think you have chaos with the menus.
Which menu type is the link "recent-topics" in flash menu?
You cannot Kunena menus use in flash menu. Does not work. It must be the type "alias"!
Please try "How do I restore my Kunena menu?"
Then create extra the links (menu type = alias)" for the Flashmenü.

Hello rich, thank you very much for your advices and sorry for the late reply. I needed to test a lot before I post.

Ok, I restored my menu.

Some menu items in my menu were indeed no item aliases.
I have removed completely ALL forum related menu items and trashed the trash.
I needed to do this several times because there were still some forum related links left.
Finally it worked out.
I removed also the Kunena Menu.
Then I created a new kunena menu (it was added with all 10 menu items).
I added 4 new links to my top menu (Forum >>> Forum Search, Forum Rules, Recent Topics).
All are item aliases from the kunena menu. I left the aliases fields empty.
I have also now a clean new forum menu.

The "Fatal error: Call to a member function..." Error still appears when you click on Forum or one of the other 3 links. F5 helps to continue.

I have read here , here and here which are all helpful threads and which I followed but finally the error is still present.

As we know, this problem was started and resolved (!) a couple of months ago but this topic was resurrected to deal with one case where (as far as we know) the recommended solution has not worked. Let's review the situation.

In this case these are the relevant Joomla settings that need to be reviewed:

• Global Configuration » Server » Cache Settings » Cache
• Global Configuration » Server » Session Settings » Session Lifetime
• Forum Configuration » General » Basic Settings » Session Lifetime = 7200

Our suggestion is to turn off server caching and make Global Configuration session lifefime (in minutes) the same as Kunena session lifetime (in seconds). If Kunena session lifetime is 7200 seconds, make Global sessions lifetime = 120 minutes.

Top-level menu items (in this case, the menu that contains the item labelled "Forum Interact!") should be of the type alias menu. Here is a screen shot that shows you what you should have:



If, after using the above recommendations, you still have the problem, examine the file ../administrator/components/com_kunena/libraries/integration/joomla16/access.php at around line 57. The original code appears below: One suggestion to resolve the problem that people were having - and it's not one that I've tested or tried myself - is to make the following change: I'm running out of suggestions.

I left the aliases fields empty.

I left the aliases fields empty. That's not correctly. Joomla these automatically created with the same name. Now you have several menu items with the same alias name.

I have tested your page with Opera, Chromium and Firefox now. The error message is (if you insert ../forum/recent directly in the address bar):

I don't know what these error messages mean, unfortunately.
