[Typo3] SQL Frontend

[Plank Tom]

Hi,
I placed the SQL_Frontend into the "Quickstart"-Environment. Somehow 
it's working: I get the results, depending on the UserID. the problem 
is, that I can't edit the data. Each time I click on one of the elements 
  in the frontend (edit/delete/...), I get an additional column on the 
left side with the navigation:

What has happened?
Thanks for your help.
