All of a sudden, I can't manage sideboxes via Layout Boxes Controller. I'll select a sidebox, set changes using 'edit', click the 'Update' button, the page refreshes, reports "Successfully Updated settings for box: shopping_cart.php" at the top, but the box remains unchanged. FYI, I've restarted, cleared cache, cookies, and even tried things on a different browser and multiple machines.

What the heck did I do? Help!
