Configuration Error 
   
  Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

  Source Error:  
   
   
  An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

  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.  
   
  Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. 
   
  Source Error:  
   
  The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL: 
   
  1. Add a "Debug=true" directive at the top of the file that generated the error. Example: 
   
    <%@ Page Language="C#" Debug="true" %> 
   
  or: 
   
  2) Add the following section to the configuration file of your application: 
   
  <configuration> 
     <system.web> 
         <compilation debug="true"/> 
     </system.web> 
  </configuration> 
   
  Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode. 
   
  Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.
