Object reference not set to an instance of an object. ASP.NET Error

Hi

Our main website is currently very unhealthy. We are getting the error below whenever we access any of it's pages. I have also attached the event view trace.

Does anyone have any ideas? Apologies but thisis from a non web developer, if you need anything else, please ask.

Thanks in advance
