Not to drumb up a dead thread... but I am thinking about going to IPB, so I'm testing an integration on a forum. I'm having the same problem, as mentioned above, but changing the CPaccess in the usergroups table from 0 to 1 didn't seem to help much. Anyone have any thoughts as to why this is happening. All other aspects work. I can login, cookies pass from site to site, just no admin panel for either admin on the forum?
