Our screen option dropdown menu is missing in the screen options area of Post.php
I've reset the plugins folder by renaming it and creating a new plugins folder that is empty.
I've reinstalled the wp-admin folder
I've increased the available memory
With an admin logged in the only available option is one column, if I open firebug and inspect the Radio Button there is only one label being rendered, "1 Column", but if I change the value to "2" and click on the element, a blank box appears where Publish, etc. are normally.
This seems to point to the php not rendering out that element?
Another issue happening in post.php is when a non-admin user is logged the Publish box is missing completely, if you open the screen options menu and click on "1" Column radio (the only option there as per problem above) the publish box appears!
