same issue for me... entering my login credentials but "Sorry. Unrecognized username or password."
thats both thru firefox as well as via my android phones browser... (where i think the tab i had abandonia open still had me logged in... so, whatever the bug is, it makes the site recognize me as logged out after reloading. not sure if this helps any. if not... just... forget what i wrote)
also, obviously, logging into the forum works.
