Try changing the definition of $perm as follows: static $perm = ''; if (!$perm) $perm = array(); See if that changes the caching behavior in your php rev." "Another minor point regarding this debug, Since you're not dumping all of the $perm variable, we don't really know that the user_id is the same. What if the user_id was being checked? (we know which was being modified) Would recommend debugging print_r($account,1) and print_r($perm,1) after the reset line.

Other modules with which I'm told this problem occurs: • Content Permissions • Localization client I've searched the code of these modules for some indication of their modifying the $perm variable, but can find none. I do really appreciate the help. This is driving me nuts! I can find no logical explanation for this modification, thus I'm unable to figure out a way around it. -ron
