I’m having the exact same problem… I tried wiping the db and reinstalling everything twice, plus reuploading wp-login.php, to no avail. I didn’t install any plugins. When I put in ‘admin’ along with the password, the page simply reloads. (Interestingly, I have the opposite problem until I clear my cookies and cache– i.e., when trying to log _out_ from the admin screen it also simply reloads the screen, without actually logging out. ) I know this isn’t a problem with me having my password incorrect, because when I type in an incorrect password along with ‘admin’, it both reloads _and_ tells me that my password is incorrect. Otherwise, it just reloads the login page. Anybody know what’s up? Thanks! -Dan
