I just installed umbraco and during the installation process i choose a clean one (whithout runway).
Everything appears to be working well, i can create macros, stylesheets, templates, etc but one i try to create a "Document Type" i get an error.

The related template is created and the document type appears on the tree, however one i select it this error appears on the right side of the screen:
