"stack empty" or "Value cannot be null" error when creating RTE in ASP.Net

Description

The “stack empty” or “value cannot be null” error occurs when creating RTE in ASP.Net with Visual Studio 2013 update 4.

Solution

The “stack empty” or “value cannot be null” error occurs when creating RTE in ASP.Net with Visual Studio 2013 update 4 and with the above update, due to a new feature added in the Visual Studio 2013. The new feature is a dynamic 'Browser link' between the IDE and the browser, that allows dynamic data exchange between your web application and Visual Studio.

To overcome this issue please add the following code in the appSettings of web.config file.

web.config:

<appSettings>
   <add key="PageInspector:ServerCodeMappingSupport" value="Disabled" />
    <add key="LoadEJResourcesFromAssembly" value="true" />
    <add key="EJResources" value="jsrender:true;jqueryeasing:true;themes:true;" />  </appSettings>
 

Or

<appSettings>
    <add key="vs:EnableBrowserLink" value="false" />
  </appSettings>
