Simple Facebook Connect: Can't Publish

I think Facebook changed their profiles and their apps a good bit –I’m getting this error:

If you can see this, then there is some form of problem showing you the Facebook publishing buttons. This may be caused by a plugin conflict or some form of bad javascript on this page. Try reloading or disabling other plugins to find the source of the problem.

I’ve disabled all other plugins to no avail… The web page showing how to set up your facebook app seems to be out of date –there are now all sorts of new settings that I’ve no idea how to use, and the facebook help pages don’t seem to provide answers for, like “canvas,” and other such stuff.

Any ideas?
