Yesterday I installed a 0.22 on my server to configure it for updating the forum, but login is not working.
I've also been having problems with 0.21 (autologin not working), but now it just does not work altogeter. When you login using firefox 2.0 (WXP) you appear as logged in the user list but you are not. ¿Anybody knows what is happening? you can try the test site here: http://www.tomatoma.ws/paralela
I've asked my community to do some testing, when they answer I'll try to bring more information about what browsers are not working.
