I haven't changed anything for months. When I want to insert a picture and click on the "insert picture" icon, then I get the following error message: "The server encountered an unexpected condition which prevented it from fulfilling the request. The script had an error or it did not produce any output. If there was an error, you should be able to see it in the error log." The log file doesn't give me any infos. Any suggestions how to troubleshoot this problem?

I am experiencing a similar problem, although my error message is only "Internal Server Error". I have seen the limited information in the error logs on my webhost - "Premature end of script headers: mt.cgi, referer: http://[my website]/cgi-bin/mt.cgi?__mode=view&_type=entry&id=647&blog_id=1" - but they don't contain enough information for MT support to help me yet. They believe that the error may be related to image::magick (6.2.4) and suggested that I have my webhost reinstall these modules, an impossibility since I am on a shared server. I also experience the error when I click the file attachment icon in the entry editing area.

Any suggestions would be appreciated.
