DVR 'Settings' page not loading - other pages load correctly

DVR ‘Settings’ web page is no longer loading. All other DVR pages load properly - On Now, Guide, Search, etc.

The Settings page loads the top-level links, but the lower section doesn’t load past the circular spinning arrows.

This is a several months old installation on a FreeNAS server. Relatively recently turned ON the remote access option.

Same behavior in IE, Chrome & Firefox, and when attempting to access the page from other computers.
