All of the sudden, creating or editing a view does strange things. I can create a view or template as normal, but after a couple of times editing the template, it'll all of the sudden revert to a standard WordPress Post edit screen, and the view I've been working on will have been saved as a Post in WordPress. If I am editing an existing view/template, it has done the same thing.
I have disabled all plugins (no new ones were installed long before this started). I have also been using the latest versions since they were available, but only started having this issue today.
This is extremely annoying, as I've got a very close deadline to finish this site, and every time I try to tweak a template, it deletes it.
