Meanwhile I tried a lot of things and I got one result: the following error message:
Error: Facebook Open Graph Tags cache NOT updated/purged.
URL failed: http://graph.facebook.com/?id=http%3A%2F%2Fwww.relimedia.de%2F%3Fp%3D1331&scrape=true&method=post
Does anybody know what that means and what I have to do?
Some tries later:
I deactivated all Facebook-Plugins (like: “Facebook Open Graph, Google+ and Twitter Card Tags”, “Simple Facebook Connect” etc.) except the Facebook-Connection in the JetPack-Sharing-modul.
Result: No error messages but the posts still don’t show up at my FB site.
– the posts do appear in Twitter but only the title followed by the URL of the blog post;
That’s indeed the default behaviour. You can define a custom Publicize message thanks to the box appearing right above the Publish button in the post editor.
– the posts do appear in Google+ but only “private” (in German “Nur mit mir geteilt”) instead of public.
That’s to be expected. You can follow the instructions here to change that setting:

– the posts do not appear in Facebook;
That’s the issue here. Looking at our logs for your last Publicized post, I get the following error:
Error 500 (Invalid parameter) -- More Than One OG URL Specified
It means that your theme, or one of your plugins, is adding a second set of Open Graph Meta tags to your posts.
Looking at your site right now, I see that you’ve managed to solve the issue on your own by deactivating the plugin that was adding that second set of tags.
Could you go to this page, reconnect your site to your Facebook, and then try to publish a new post?
Let me know how it goes.
