You haven't shown us the code that's causing the error. The most likely cause is that your server is locked down, and doesn't allow you to set the trust level for your own application.

However, your config file is a mess. You've set the target framework to 4.0, but you still have a lot of parts which only apply to .NET Framework 3.5 in there. You should start by tidying that up.

That's not an error in the configuration file; that's an error in your code, which you still haven't shown: MPAdmin.Page_Load
