Tried that... even rand the fix_login.php script which fixed the adminCP probs
The only thing that comes close to working for me via tester on vb3 and the live forum is the way I've mentioned. and that effectively logges users out whenever going into the vbindex page....
I've kept it this way(.noblepagan.com, /forum, /vbtest), hopefully my users won't notice lol! At least til I can find a fix for it.
