Theme – Facebook does not correspond anymore

Hi, I need your help. I have catch evolution pro theme. Since some weeks, my facebook-likebox does show up only half, like cutted in two. (before that, it worked out fine a long time) I tried to construct a new one - same. On other Themes it shows up right. Now I tried to share my newest Blog-article on facebook with facebook-sharebutton on the Blog like usual. Facebook does not find (Google+ does, also by same kind of sharebutton). If I try with older Blogs, it still works. (Newsletter-link, Google, Google+, everything works, the link works) Is there something I can do, to solve this problem with facebook? It must have something to do with the theme, because the likebox is ok on other themes. Thanks Elisabeth
