My problem with it is at this point the pages load like a 2nd grader wrote them. Code is displaying on the page instead of doing what code is supposed to do...stay hidden.
The main page alone looks like this:

The subsequent pages load as straight strings of text. I entered in the database info as it should be and built the tables. The extent of my php knowledge can't make heads or tails why this is doing this. I want to reverse engineer and learn how the system works but...it doesn't work lol. Is it just old code or something? Halls codes in a completely different way than this.
I'm mainly interested in how the admin and mail functions work.
