I've just installed DNN for the first time and after fixing many problems have finally got it to install and display the home page. However, I'm now seeing the following error whenever I try to do anything useful with DNN:
A critical error has occurred. Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
My Googling indicates this might be a trust level issue, so I've tried increasing the trust level (in the trust tag in the web.config), however this results in DNN just failing silently whenever I try to do anything.
For example, in the Admin -> User Accounts page, when I try to add a new user with trust level set to medium in web.config, I get the error above displayed in the toppane area. When I try to add a new user with high trust, nothing happens at all. The page is fetched and re-rendered, but no form to add a new user is displayed. The same behaviour occurs with full trust.
The same behaviour occurs in pretty much every peice of functionality across the site which I would expect to render a form of some sort. I can't display or edit my own user profile. I can't manage other users. I can't add any new pages. And so on...
As stated, I've tried Googling this issue, but nothing I've come up with seems to help. For reference, I'm running XP Pro SP3. I had a number of problems installing DNN, including the redirect loop issue which I fixed by adjusting web.config to use the framework 3.5 ajax controls. I'd appreciate some help with this issue as I'm really stuck presently. Thanks.
