1) I intalled severel Plugins (see attachment), extensions and components
2) Then the Preview didn't work and gave me the information: Error, Error generating preview contact administratot (see attachment)
3) I made the new plugins inactive (plugins see attachment)
4) Preview works now in general, but very wrong (see attachment)
5) Dashboard (attachment) in comparison
What can I do? What was the problem?
Thank you !:-)
