Errors after publishing an article

Hi again,

Since the 2nd latest Update i get always an error message after i submit the post. with the second latest i got the Joomla error 500 page, After that i updated to the current version and now i get internal server error 500 of my hoster. It shows the page of my hoster not anymore the one from joomla.

Its always after i submit a post. has it something to do with the facebook posting problem? I havent applied the hotfix yet but it is still posting to facebook....


But the article itselft gets created and also published how its should be. i just get always this error message afterwards i hit publish...
