I don't know if anyone is experiencing this issue. When I try to add a link to my Facebook wall, Facebook normally pulls images from the link. You can navigate through thumbnail images if there are multiple ones, to be showed as thumbnail. First I thought this was a host related issue. But on the same host when links from joomla or Wordpress can accomplish this, XenForo can't. Also some users in our community are experiencing the same thing (problem). It this designed this way or is it a software problem ?
