Ok, sorry for doubbleposting here now. But everything worked now for me, except the notebook of course :P
I can still see the frontend with the active worksheets and I´m also able to create new ones, but I cant edit them or write something on them. If I enter the URL (eg http://localhost:8000/home/admin/1/ ) on the VM, it shows an error page. (HTTP status code 500) :( -- You received this message because you are subscribed to the Google Groups "sage-devel" group. To post to this group, send email to sage-devel@googlegroups.com.
