i think i maybe found the problem, my comprofiler_members table is completely empty, even when i sync users it stays empty.
i am using a different prefix for the tables but i dont think that is the problem.
next to that, when i made a new user in the backend i got this message
Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 46080 bytes) in /chroot/home/tsfknl/ts-fk.nl/html/administrator/components/com_acajoom/classes/class.module.php on line 205
does anybody have any idea?
