Forum OpenACS Development: File not found error when clicking on bug tracker in PO

I first deleted bug related data from the back end tables to remove the closed
bugs from the list. That caused a duplicate key violation error on cr_items
index when i tried to add a new bug. Then I uninstalled and reinstalled the
bug tracker package from the admin tab. I checked all the backend tables manually
and all other parameters are set, but still, when i click on the bug tracker i get a
"FILE NOT FOUND" ERROR.

Any clues how to fix this? Please help
