PHP 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 found the error occurred after waking my computer from sleep. With the web browser still open to the Kunena "Recent Topics" page I went to reload the page and got the 500 error. I hypothesize this has something to do with trying to reload the page with the original session long expired. Loading a different web browser on my computer, the page loaded with no error.

In the file mentioned in the PHP error log (/administrator/components/com_kunena/libraries/integration/joomla16/access.php) on line 55 it turned out $user was being set to null, which led to the error on line 57.

My solution was to put the following PHP code on line 56 to force the Joomla session to restart:

Code:

if(is_null($user)){jimport('joomla.session.session');JSession::destroy();}

The error ought to go away without this fix if you restart your web browser, or if you log out of and into Joomla again.

This. Seems to happen occasionally if the session corrupts to some degree. I also think ACL controlled forum sections are partly responsible.

Thanks for the temp fix.

Hello,

I am experiencing the same issue and the fix doesn't work, after server reboot/browser cleaning/test on a new computer etc.

Apache's error_log is full of:

mod_fcgid: stderr: PHP Fatal error: Call to a member function authorisedLevels() on a non-object in
[path to website's folder]/public_html/administrator/components/com_kunena/libraries/integration/joomla16/access.php on line 56

Followed by:
mod_fcgid: stderr: PHP Notice: Trying to get property of non-object in /[path to website's folder]/public_html/libraries/joomla/factory.php on line 223

it goes like this ad nauseum.

Here is my config:

Database collation check: The collation of your table fields are correct

Which "fix" was that?
