I have an issue with the DNN DocumentLibrary. I made a tree for my document-folders with subfolders (in the DocumentLibrary).
Via Admin - Document management / file management I deleted some subfolders.
Now, the DocumentLibrary has stored references to these deleted folders (I can select these deleted folders when I wish to restrict the tree-view to a certain folder in the module). When I want retrict to a parent folder from which I have deleted some subfolders (which still can be seen in the DocumentLibrary), the module gives an error; an object reference is not set to an instance ....
My question is how do I delete these references to the non existing subfolders so the module doesn't crash anymore whene I choose certain folders as restriction?
Thanks a lot.
