Having more issues with login.... I got that jfusion plugin you talked about, it succesfully intergrates my forum with joomla, however I am back to the login doing nothing on the front page... When I enter my user name/PW page seems to reload, however no error message, no login confirm, login fields are still present. Login with facebook = same result.
(Oh by the way, jfusion wasn't able to install its tab component or whatever, so i must enter URL manually to get to the config part of jfusion. other than that, appears to not have any issues...?
