How to track and log Profile Admin activities after login?
Using Jamroom
2) (guess) if the standard joomla .htaccess reads "take any url coming in and re-write it to index.php" then your going to need to exclude the /jamroom/ directory from that re-write rule.
Jamroom's .htaccess does a similar thing, it takes any url directed at it and sends it to router.php for processing.
May be that joomla doesnt like having a different CMS system living within its directory structure.
