Seemingly overnight, my Administrator accounts no longer have the ability to create new posts or new pages. Yet other admin functionality remains intact like editing theme files and modifying previous posts. Instead of a Publish button, they have a "Submit for Review" button. Things I've tried already:
-Checked the database tables (user meta, options, user roles, etc) and everything seems to be normal there.
-Created new admin users.
-Dowgraded current admins then promoted them back to Admin.
-Disabled all plugins.
-Changed to default theme.
-Installed a user role management plugin.
-Confirmed with my host that we haven't hit some sort of capacity limit.
None of these things resulted in any change. Getting a little desperate since the site is essentially bricked right now. Thanks for any advice you folks might provide.
