I started to build my site with ASP.net MVC and then choose to use web forms instead. I had already upload some test pages, so I used a ftp software to delete the old files and then upload the new site. Unfortunately, I must have deleted something critical that was not part of my original build. i am now getting the below security exception error when attempting to go to my site www.godflood.com. I'm using visual studio and the site builds fine and test good on my local host. 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 found this similiar thread and fixed it by adding full trust to my web.config file https://forum.winhost.com/threads/security-exception.19055/#post-36861
