Mfazalb,
Strangely enough, in v4.2 and 4.3, if you enabled the RokBooster plugin, you would have run into the same issue. At that point RocketTheme's 'optimization' plugin was replacing any instances of:
with
In other words, they were removing the fb: from the statement, which was required. You can see the note about it in our
v5.0 changelog
"Enh: Compatibility improvements with RokBooster by RocketTheme
The change we made was to move to the newer methods that Facebook recommends for implementing the widgets, which is to use the following tag:
<div class="like"> </div>
So, I don't know why that specific RocketTheme template is stripping out the code between the scsocialbuttons tags (which you can see on the page). It's not happening with other RocketTheme templates and it's not being caused from a system or content plugin. The only remaining 'unknown' is the specific template that you're using. And again, we've seen RocketTheme extensions modify our code in the past.
I don't have an answer for you, and I'm not sure I'm going to be able to get you one. I'd highly recommend contacting RocketTheme and ask them if they have a clue as to what may be happening. I don't know their template architecture or know all that goes on in them, so it would be difficult for me to diagnose.
The only suggestion I have would be to use v4.3 until we have an answer from RocketTheme. If you want, I can send you JFBConnect v4.3 through Private Message and you can use that.
Thanks,
Alex
