When I logout of the admin area on Firefox ver 48.0.2 I get the following error: (my username replaced with "username") Warning: Error while sending QUERY packet. PID=29738 in /home/username/public_html/member/library/Am/Lite.php on line 581 Fatal error: MySQL server has gone away in /home/username/public_html/member/library/Am/Lite.php on line 910 Workaround: Can be resolved by clearing cookies and cache. Figured I run it past the forum to see if it's repeatable by others before sending to the bug bin. Running ver 5.1.5
That means for whatever reason the Database connection was lost, the code can't process the logout. If it is just spurious don't worry, if it is common you need to have your mySQL looked at.
