I don't know the site structure, so it's difficult for me to know what an article is. I see a lot of sales pages, but unsure if those are generated from articles. If you can help provide a link to a page that has an issue and any details about how you've set JFBConnect to show social widgets on that page, that would really help. For instance, are you using the JFBCContent plugin and configuring it in the "Social" area in the JFBC admin area, using some of our modules or using the EasyTags, like {JFBCLike} on the page?
Any details you can provide about what isn't working will really help us narrow things down quicker.
Generally speaking though, our modules can go in any module position, our Content plugin will work anywhere that "Prepare Content" is called on the content (articles, some modules, etc) and our Easy-Tags should work anywhere.
Thanks,
Alex
