Webmatrix site - Security Exception - Shouldn't be there

Question

I have just uploaded a site and it's throwing a Security Exception at me. The client does not need a database or Register/Login functionality or even email setup, so I am not using anything like that.

All I have in my pages (just one page at the moment, with a SiteLayout and Default.cshtml file), is just plain old HTML and CSS.

The error and stacktrace is:

Server Error in '/' Application.

Security Exception 
  Description: The application attempted to perform an operation not allowed by the security policy.  To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

I'm completely stumped as to what to do next. Any help will be greatly appreciated!

If the hosting you are using is shared with another websites, it's likely that the application security level is set to Medium Trust and some part of your application requires Full Trust.

Here is an article that explains a bit more of Medium Trust environments.
