I've created a new member for a website (that I'm making for myself) to see if it works and when I register, I can get in, but when I go to log in after, it won't let me log in and I can re-create the same member multiple times.
The code that I have that's giving me the error is:
do_html_header('Warning:'); echo 'You have not filled the form out correctly. Please go back and try again.';
