Sorry for the delay in answering this. Briefly looking at our changelist, there's not anything glaring that would have changed in a newer version of JFBConnect that would be broken in the older 6.4.1 version. I think this may be how you've configured JFBConnect, but we'd need more information on how you've set things up.
We provide several ways to add Open Graph tags to the pages, which can be described in
more detail here
. After making any of the changes to add tags, you'll then have to re-scrape the pages on the Facebook Open Graph Debugger
1. Our Open Graph plugins - add an object on the backend for supported components and we will determine the correct tags to add
2. Add specific SCOpenGraph easy-tags to the page
3. Add default tags to the site when none are found on the page yet
4. JFBConnect will automatically add some tags to the page if none are found.
The link you provided does not load for me. Please provide specific URL's that I can run through the FB debugger and view the source at and describe how you've configured JFBConnect to add the tags.
Additionally, sometimes there are other issues that can cause the wrong images/previews. Please see our
Common Support Questions
for "My Share Preview is Incorrect" for more troubleshooting tips.
