Rou,
The og:url tag being generated looks like:
https://www.rouride.com/store/grips/glitter-grips-blue-rubber.html?format=html&lang=en
When I go to that URL, I am redirected to a different page with a different URL than the original. Not sure why the URL is being generated like that. JFBConnect simply tries to use Joomla to generate the proper URL for the page.
Can you let us know what SEF extension or any other URL modifiers you may be using? Also, try re-ordering the JFBCSystem plugin to either the first or last ordering and try to run the Facebook URL debugger after each. Hopefully one of those ordering positions will fix the issue by making sure your SEF or language extensions are (or aren't) already loaded when we try to generate the URL.
Let us know how that goes!
Alex
