Ultimate Facebook Plugin - won't post to facebook

Hi,

I tried everything and I can't get this thing to post my posts to FB. I tried another plugin from wp.org and it worked great. I figured I would switch to this because of all the features. I too can't get the default comments to stop showing when I want to just have FB comments showing.

Can someone help me look at this?

Thanks,
Scott
