I think I know what caused the error. However I couldn't try to duplicate the same problem because I don't have access to install WP Total Cache.
I tried to deactivate both types and views, but still see the error so it's definitely something else. I use WP total cache, and when I deactivate that plugin, the error disappear but of course I need cache for my site. Clearing the cache alone doesn't work.
Can you give it a try?
