I've setup an iframe application in facebook through the Dev protocol. I figured I completed all of the variables properly however the Application DOMIAN in Fundamental INFO is blank. It will not accept anything I place in there.

I examined my URL and my iframe graphics appear fine.

After I visit the actual facebook page and follow the link, I recieve the 405 missing page error.

I'm able to only assume it is the missing Application DOMAIN.

Can anybody advise?
