Pages not showing

[Piapia]

Hello,
the pages I have created in the past suddenly don't show anything anymore except the menu (the source code looks like they should though).
projects work, categories work, new pages(!) work. can you help? i tried duplicating the old page (with duplicator) but it didn't work.
