Conflict with JomSocial

Yes, that should be disabled, but that's likely not the problem. You should also have the settings in the JomSocial config area for Facebook connect all set to "no" with the API/Secret key settings blank.

With that said, can you describe a little more about what's happening? What posts are showing up twice?
* Is it a post someone makes from your site being duplicated.. I could see this can happening with the PostToWall JFBConnect plugin enabled.. the post is on JomSocial.. we post it to Facebook.. then, the user logs in and it gets pulled back in. We have checks to prevent this, but possibly missed something.
* Is it a post that was made on Facebook? This could be from the "Import User Status" setting in the JomSocial profile plugin. Again, we have checks to prevent duplicates, but possibly some weird configuration.

Let us know some more details, and we'll help how we can. This isn't something we've heard of before, which means it's probably some configuration or minor conflict that we should (hopefully) be able to resolve quickly.

Thanks,
Alex

No problem. Let us know if it crops up. That was an issue, briefly, at one point. Hate to hear it's back again, but as JomSocial updates and Facebook changes, there's always a possibility of bugs surfacing.

Good luck,
Alex
