Custom Username/Usertitle/Post Formatting

[Switched]

I think there is a problem with this or it could on my side. Whenever I try to activate this I get a blank white page or if the database table is there I get an MySql error saying it is already there. Since it put the sql in is there way I could manually do the code edits to get to work or something and yes I have entered my ftp details so it can do that file edits.

EDIT: Ok wow I'm dumb, I found where it tells you want to do. Great plugin!
