If receive error logging into WBI "Session state can only be used when enableSessionState is set to true ..."

If when logging in via WBI, you receive the error message (full screen shot is below): dir=ltr " ">

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 the System.Web.SessionStateModule or custom session state module is included in the <configuration>&lt;system.web>&lt;httpModules> section in the application configuration

The reason most likely is due to having replaced the installed Web.Config file with an old version of the Web.config file that does not contain the correct configuration statements.

To resolve:
-un-install AyaNova WBI
-Open Windows Explorer and make sure the AyaNovaWBI folder (andall of its files)is completely removed if not already.
-Install AyaNova WBI
-complete the WBI installation and testing steps again.
