Please upgrade to JFBConnect v6.1.1 (or v6.1.0). Older versions of JFBConnect had a 'fix' for SSL enabled websites that was required for how LinkedIn used to work. That fix is no longer required and actually causes the image to not appear properly. The problem only occurs when your site is loaded over https. Again, it's fixed in the latest releases.
I hope that helps, but if you have any questions, just let me know.
Updated to the latest JFBC & SCLogin versions as of today, 7/21/2014. Linkedin Button appears normal now, but the FB Like & Send buttons have disappeared completely on every article. Ran AutoTune and everything is green now....however, when I ran it (after updating the components) I had RED on the De-Auth URL & Callback and also on the Site URL (the site URL was probably because we are forcing http to https on the domain?). So, all GREEN on the AutoTune but no FB buttons now...
I just looked at your https://ax...ww.com site. Let me know if that's not the correct one.
On that page, I don't see where the FB buttons are even being tried to be inserted. Can you check the JFBConnect -> Social configuration area and make sure they are enabled to be shown? Not sure why that would have changed when you upgraded, but possibly that setting got switched somehow.
Even if it looks correct, hit "Apply" to make sure everything is saved properly.
That was it...the Show Facebook button in Article view was set to 'No". I assume something in the update of the JFBC component caused this since the buttons were visible prior to the update. We have a couple other sites that need JFBC updated, I'll check to see if those are effected in the same way...if so, I'll let you know. Thanks!
