Properties for Search Service Error

I'm using SharePoint 2013 and have provisioned the services I need successfully. I've setup Search Service also successfully and it is functioning properly. However, when I go into Service Applications and try to view the properties I get the following:

Sorry, something went wrong

An unhandled exception occurred in the user interface.Exception Information: 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. Technical Details*

Looked at my ULS logs and this is what gets logged:

I also get something similar to this error when I view the properties for BDC, Secure Store Service and Visio Graphics Services. any help would be greatly appreciated.
