Register with no password?
Here's the deal. I added a few lines to the register.php page to help prevent bots and spammers from joining, and I don't know if this caused it, but now you're able to register with no password entered into either password blank.
Any ideas? It's really bad because you could register, be auto logged in, and if you log out, you'll have no password (or a blank one maybe).
Here's my register.php code:
