Wrong url chosen for like button

Lionel,
Something on your site is redirecting Facebook's search robot to the mobile version of your site. You can see what's happening using their URL debug tool below:
developers.facebook.com/tools/debug/og/o...d%3D51%26Itemid%3D67

On there, there's a redirection to your mobile site using a 303 HTTP code.

You'll need to fix or disable whatever's causing a redirect for a Facebook User Agent, and it's not JFBConnect that's doing that.

Hope that helps,
Alex

Glad to hear we helped. If you need anything else, just let us know.

Finally, if you haven't already, please consider leaving a rating and review for JFBConnect, or our support, on the Joomla Extension Directory. It's certainly not required, but very appreciated:

Thanks, and good luck,
Alex
