Facebook Ultimate on Sub Blogs

Have the plugin set up and working, but it only works on the main blog. The sub sites/blogs, it opens the facebook login box, but then nothing.

Main site logs in fine. Subsites do nothing.

Settings in the network admin are set to use the same for all blogs and not allow them to edit the plugin individually. App is configured to the main root mysite.mysite.com/

Subsites use folders ... mysite.mysite.com/site
