I have DNN 4.8.1 installed on Windows XP SP2 / SQL Server 2005 Express. I did an automatic install and created 2 portals. I then installed the DNN Gallery module (v3.0.12), and added it to a page in my first portal.
When I tried to access any of the gallery menu items (add file, add album, maintenance, etc) I got the error below. I read other messages on the forum, and modified line 16 of ControlPager.ascx - this didn't help. I then noticed that the URL in the address bar when I got the error was http://mydomain/Photos/..., and realised that I had created a subfolder called "photos" in my dotnetnuke\mydomain folder, with the intent of putting my photos there. So I deleted this folder (it contained one photo, which I had put there).
After doing this I started getting the error below when I tried to access any page from either of my two portals - i.e. my DNN installation now appears to be completely "broken". I've tried restarting the server but it doesn't help. Could anyone offer any advice?
