okay, we are making progess.
I originally imported my info from a php-nuke portal into vbulletin. using impex i imported my users. now, when i did this i left my vbulletin with no prefix. and my nuke tables all had a prefix of nuke_
when i leave the bulletin prefix box blank i have the same issue as above. if i change it to nuke_ i show all of my registered user's but seem to be logged out when logging into the admin cp for photopost. it re-directs me back to the photopost main page.
i checked my cookie settings in vbulletin and they are totally blank. i also tried adding my domain onto them .hondaracer.com with no luck.
