I get a white screen when I try to save my custom post type.
I have 3 separate sites that I run, all on the same server, even stripped down running theme 2011 and no other plugins, I still get a white screen when I try to save my custom post type.
FWIW, Custom Post Type UI will create a Custom Post Type for me, I can then use Types to create the custom Fields.
Does anyone know how I could track down the problem with Types?? If it is not executing, how do I track down the errors?
