Contribute 3 help

Hey all. I just got Contribute 3, but I when I try to be administrator on a webpage it asks for a Guard Page, wich is suposed to be the index file I guess. But whatever I do, it wont accept my index.html file, neither any other files.

Anyone that knows Contribute 3 that could help me here? Cause I’m kinda clueless atm :frowning:

Thanks,
