I've installed my xf1.2 in a subfolder /community and link to the login page using this url:
Users are logged in but they are redirected to http://www.mydomain.com/community/login/login which causes an error message: "a security error occured". If they click on the forums menu tab everything is fine.
Unfortunately the less experinced users are irritated.
I have no idea where this redirect comes from. Any ideas?
