Extended Permissions just hanging...

I've created my Facebook app, connected and all seems to work on FB. Gone through the Ultimate set up routine. When I get to Grant Extended Permissions it just hangs. I can skip and fill in the rest of the values further down fine and can see (for example) fb like buttons under posts.

I'm wanting the app to post to a page but the option to do this has not come up, is this to do with the extended permissions not being able to be set?

How do I fix this please? :wink:

Thanks,

Simon
