Howdy all,
Thanks for your patience and understanding in this matter. I just wanted to let you all know that we just posted a new Social Modules zip. This package has version 3.2.2 of the JFBCComments module, and we'd recommend you upgrade to it if you're using that module.
3.2.1 has the "Legacy Mode" option to enable XIDs
3.2.2 adds a bug-fix posted by Wes in another thread. This bug caused replies to comments, when initiated from a Facebook wall, to be posted to the wrong URL on your site.
Again, thank you all for your feedback, and if you have any other issues or suggestions, let us know!
