Server Error in "/" Application

Greetings,

I downloaded the NopCategoriesHeaderMenu for 2.65 and uploaded the two folders to my plugins directory. But as soon as I hit re-load plugins in Admin, I get following 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.

The moment I remove the two folders, there is no error. Please help.

Hi Pratik,

Could you try first coping only the Core pugin folder and install it.
Then copy the Header menu folder and install it.

Hey,

Thanks for the reply. I managed to install the plugin successfully, however I did with some other method. When I copied two folders to my website pluginf folder, the plugins got installed automatically. I had to first uninstall both items and than install again both of them as per install instructions. That did the trick.

But now I am facing another issue. The menu stops working at random times and starts working on its own at other times.

The error that shows up when it stops working is this...

Hi ginc2000,

Is there some pattern when it stops working?
Is there something that causes it to stop working i.e some specific action you do?
Are you working locally or it is installed on a web server?

Best Regards,

No, I don't see any specific pattern when it stops working.


I have no clue why and how it stops working. I am sorry for not being able to point to any specific direction


We store is installed on web server.

This is the store url www.pbfstore.com

Today its not working again as of writing this.

Hi ginc2000,

We can not open your website. Please fix it so we can try and find the problem with the Menu.
