I am trying to activate the View Mode Page module because I need to use URLs to jump from one view mode to another. From teaser to presentation to full node. Every time I try to activate the View Mode Page it gives me an error and after that I am unable to view the Manage Display section for any of my content types. It mentions there is an error in the view_mode_page.module (or something similar). Does anyone know if this module is incompatible with some other modules or what the problem might be?

Thanks in advance.
