title: Registration data not being sent to my database
body: <p>My login is working properly, but my registration seems to not add the data to my database. I have tried to solve the problem for a long time with no luck. Maybe some of you "bright" people can help my dumb ass lol! Nevertheless here is everything: If you do help me, thanks in advance, btw I think it is a problem in the Register.php!</p>
