Renas,
That page is returning a 302 response code, which means that page is trying to redirect. Facebook is seeing this redirect and that's causing issues, because the redirect is to the same page.. That's causing a loop, so Facebook can't see any of your tags.
You'll need to fix that issue, but I don't know what's causing it. It's not from JFBConnect. If it only happens when that slider is enabled, you'll need to contact the slider developer.. though that seems very strange.
You can check the response code with the tool below. You should see a "200" code, instead of the 302 that's being returned:

Hope that helps,
Alex
