Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \\ section in the application configuration.

Exception Details: System.Web.HttpException: Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration>\<system.web>\<httpModules> section in the application configuration.
It's an error that could make you loose some of hair if you don't get some precautions. 

How to proceed to solve:


  • Verify if your enableSessionState is set to true. There is a tag in your web.config file, as you can see here: 

<pages enableSessionState="true" enableViewState="true" enableViewStateMac="true" ..

  • When you're still looking the web.config check the httpmodule: 

<add name="Session" type="System.Web.SessionState.SessionStateModule" />

    Also had the same error. We moved a Web Application from SharePoint 2010 to SharePoint 2013 Environment. And on the SharePoint 2013 Environment this was not set to true. So I did the steps above on the 2013 Environment and the Issue was gone.
