I am not sure why this happen and because which mods this happen. After user registered, and they input their user id and password, it always redirect to the login page. Anyone had a trouble with this before? Please share the solution here ... Thanks.
This for all users, or only certain ones? What forum software are you using? Check the cookie settings in your ACP. Also have the user try clearing their cookies and see if that helps. Usually this behavior is due to incorrect cookie settings for your forum. BMR777
Thanks for reply, yes I think so its because of cookies and vBclassifieds mods's effect. I tried to remove the "www" at forum to access it also set cookies and so far its running well. Thanks, Pluie
