Question Error Message: Kunena: Failed to save session information!

Hello,

We have been using the Kunena forum for quite some time now. All of a sudden, the forum crashes with the message - "Kunena: Failed to save session information!". The additional information supplied is "Invalid argument supplied for foreach() in...

...libraries/joomla/database/database/mysql.php on line 383".


This error is occurring intermittently and normalcy is restored again after logging out / logging in by a user.

Thanks in advance.
