iOS Facebook connect issue with post

I can't get a facebook connect post to work. The odd thing is the actual post itself works when the publish button is clicked. But for some reason the actual post dialog doesn't have any content between the "Post to wall" and the buttons on the bottom. I've tried running it w开发者_JAVA技巧ith the demo app too, same result. This worked last week. Anyone come across this? Here's my dialog code.

NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:content.siteUrl, @"link", nil];
[appDelegate.facebook dialog:@"feed" andParams:params andDelegate:self];

Try this:

[appDelegate.facebook requestWithGraphPath:@"post" andParams:params andHttpMethod:@"POST" andDelegate:self];

The fix was on facebook's side. It's back to normal now.
