Blunt is fine.
In the thread above is a link to an updated JFBCComment module, version 3.2.1:
* This is now included in the Social Modules zip *
If you can specify how you're including the Comments on your page, if it's not the Comment module, we can help you determine the best way to fix the issue.
Again, right now, there is a bug with the old XID based comment widget. This is not related to JFBConnect and was introduced by Facebook itself last night. The bug report for this issues is:
bugs.developers.facebook.net/show_bug.cgi?id=16484
We recommend moving away from the XID approach on as many pages as you can as Facebook may drop support for this method at any point in the future. At that point, all comments on the older style modules will be lost.
Hope this helps, and good luck,
Alex
