I've upgraded to the latest Umbraco, and everything seems to be working apart from the DocTypes.

If I open up a docType I get Object reference not set to an instance of an object error? Anyone else get this? Was there a config or SQL db change I need to check for?

Object reference not set to an instance of an object.

Stack Trace:
