Can't post to facebook

I’ve followed all the instructions which seem simple enough… But I have no capability to publish posts to my Facebook account. The post edit page gives me this under Facebook Publication: 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.

Pleas help me..

I was able to get the like button on my posts, but I’m not sure if I created the App correctly in FB. Any guidance would be appreciated…
