PHP Version 7.0.19

Ok, so I decided to install 1.2.31 because I really like the phpBB 2 style that I found for it. Everything installed ok and works ok after I changed some mysql version stuff in install.php except now when I make a post it only show's the post's title and not what I write in the text area. Any idea how to fix it?
Take a look here to see what I mean:
