Hi, When I share my posts on FB I can choose miniature from the post and it works, but when I share my main site www.poradnikniemowlaka.pl there is no miniature. I checked the debugger : http://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fwww.poradnikniemowlaka.pl%2F and there's one warning but I dont know how and where fix it. After that I added one plugin http://fedmich.com/tools/facebook-and-digg-thumbnail-generator but it didnt change anything. Can u help me again ? Thanks, D.
