Object reference not set to an instance of an object

Hi,

I run dotnetnuke version 5.2 on localhost, most of which are working fine. but when I run on web hosting, I get this error:

Server Error in '/' Application.

Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

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.
