I have traced a strange bug down to when gforms is activated it prevents an admin user with the Editor role or lower from seeing any Posts (wp-admin/edit.php prints the top very top gray menu and then the entire rest of the page is blank).
I assume it is a privilege issue as everything works fine if I switch the user to Administrator role (or turn off Gravity Forms).
I am not using the Members or any role management Plug-in.
