To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Answer 1

it's getting cause of server security level limitation, you need to fixed this in your Web.Config file.

or

you can asked to Serve Vendor to change the Security Level for your Host.

<system.web>
  <securityPolicy>
    <trustLevel name="Full/High/Medium/Low/Minimal" policyFile="internal"/>
  </securityPolicy>
</system.web>
