The last time I made a post I didn't have any problems, but now apparently I cannot login. After entering in login information there's just a blank screen at wp-config.php. If I enter incorrect login details it tells me that the login is incorrect as it should, but if it's the correct information, it just halts on a blank page.
I don't think it's a plugin conflict because it was working fine just a few days ago. Are there any files that I should replace by FTP?
