Dear All, in the meantime I fixed this problem by installing a fresh Mezzanine 4.2.2 environment and copying over my projects. This works (after getting static files and templates right).
ONLY ONE issue remains: If I want to add a new page I can do so using the top level *add page *menu; unfortunately if I try use the menu to add a sub page for an existing page the menu is empty. After looking a bit through the source code I suspect it has something to do with permissions but I am not sure. If you have any suggestion .... Thank you very much Gerhard Am Mittwoch, 14.
