When adding a page to several of my portals (some do work fine), i receive the following error:

System.NullReferenceException was caught 
  Message="Object reference is not set to an instance of an object."
  Source="DotNetNuke"
  StackTrace:

  InnerException:

I apologize for the partly dutch stacktrace, i used the dnn source package to find out where the error occurres, The errors occur since my admin tabs were deleted from the tabs table by dnn no clue why that happend bug?  Tabmodules and modules are still intact. I just restored all admin tabs, this didn't solve anything.

Seems that the problem was caused by 1200 rows in the tabmodules table that pointed to none existent tabs. I deleted the rows and my problem is solved now.
