I have a program that performs the login to Vbulletin from non-Vbulletin page. This integration has worked flawlessly in Vbulletin 3.8x and all 4.0 beta, RC and 4.0PL1. I upgraded to 4.0.1 and neither login or logout will work from the non-Vbulletin page. This mod changes no Vbulletin code at all. I am seeing other threads about login, cookie and remember me kind of problems. User have trouble logging in
Is there a known problem that occured for the latest release that may be corrected for next update. I do nto wish to spend a bunch of time and get a programmer to try to fix if there is potential issue to be corrected.
