I found the problem, I had a very old version of the hack

(shoot me now for acting like a total n00b, I haven't slept at all :nervous: )
I now have another problem... Although I set everything correctly, updated the pages I wanted to include it, adjusted it's settings etc etc etc nothing shows up...
Sorry if this has been asked before but I'm writing exams in a few hours so my time at the moment is extremely limited... I just sat on the pc to drink a coffee... :nervous:
