I was late joining the discussion -- and posted a new topic about it because I hadn't seen this one -- but Tristan's advice cured the problem. Thanks, Tristan....
Two things: I cannot log out using my default browser (Firefox) and my totals never update. But when I log in using Internet Explorer, I can log out and get updated totals.
There is, at the top of my gridrepublic screen the following message:
Notice: Undefined index: userid in /var/www/vhost/www.gridrepublic.org/joomla/smf/Sources/Load.php on line 362
What does that mean? And what do I do about it? Is it related to my logout/updated totals problem?
