ASP.NET

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

Details: To enable the details of this specific error message to be viewable on <br> remote machines, please create a <customErrors> tag within a "web.config"  <br> configuration file located in the root directory of the current web application. <br> This <customErrors> tag should then have its "mode" attribute set to "Off".

<!-- Web.Config Configuration File -->
<configuration>    
   <system.web>        
      <customErrors mode="Off"/>    
   </system.web>
</configuration> 

Notes: The current error page you are seeing can be replaced by a custom error <br> page by modifying the "defaultRedirect" attribute of the application's <br> <customErrors> configuration tag to point to a custom error page URL.

<!-- Web.Config Configuration File -->
<configuration>    
   <system.web>        
     <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>               
   </system.web>
</configuration>
