login conflict

[theloller]

hi all

i'm using this hack:
https://vborg.vbsupport.ru/showthread.php?t=173693

it work fine, i can see the form and joing trough the form, but also if i'm already logged, it continue to show me the form.

i think that i could have some kind of conflict with the cms i'm using.
(i just want people join the forum, not the cms, so i don't need the cms login)

it's and adult cms, so i don't know if can i post the name of this cms (maybe someone have already solved this problem)

i have created a test.php and it work great.

search here is really massive, so i can't find nothing :|

please heeeelp me, also with a little tiny link ^^

thanks all
