Since I installed the latest version of WordPress to 3.7, the Edit Flow plugin has been posting warnings every time I go to view the posts area. It breaks my installation actually.
Here are the screenshots:
This image is of when I am logged into the admin panel and just clicked on the Posts section.
This image is of me scrolling down the Posts section and you can see the warnings for every post.
I have no idea what is causing this but I've had a few problems since the update of WordPress with other plugins such as WordPress SEO. I had to uninstall Edit Flow and WordPress SEO until these issues get fixes. WordPress SEO was literally breaking my website with white screen and warnings.
