What’s the url of your Facebook application?
What’s the url of the “check permissions” page you are getting?
The errors you are seeing – Parse errors from FBML – basically mean that for some reason WordPress is trying to output a full HTML page, while Facebook is expecting an FBML page.
Generally this happens as a result of a bad setting in the FB application itself, specifically what kind of canvas page is expected: iframe or fbml.
I just checked with 2.3.1 on my own blog and the check permissions is working fine.
Talked with DAKing on twitter – changing settings for FB back to iFrame fixed the FBML issues.
Updating to 2.3.2 fixed the posting to fb issues
