I have 2 dnn instances, one is on my local computer, the other is on our central dev server.

Today while using the filemanager, either as host or admin I started getting some errors.

First error is after going to the file manager and selecting any existing file from the right
pane and then clicking on the checkbox to tag the file, I receive an page error message
in the lower right corner of the screen, if I click on it and pick show details.
I get the error message:
Line: 88
char: 26
Error: 'dnn' is undefined
Code: 0
URL: http://websitename/Admin/FileManager/tabid/46/Default.aspx

2nd error is if I click on the upload button in the file manager, on my local instance the page
reloads and the file manager is replaced with a File Upload panel which contains a text box,
a browse button and a hyperlink to save the file. On my central dev server this does not
occur.

The only thing that I have changed on my central dev server is to install the Events module (03.03.07).

I uninstalled the module but this has not fixed my problem.

So can somebody point me in the right direction to fix this problem ?
