LMS 7.7.2 has lost Settings page

[Grumpy Bob]

I find this a little weird, and it's something I've not seen before. I'm running LMS 7.7.2 on a QNAP TS-239, and have run various versions of the server on this NAS very successfully. Yesterday while doing a little maintenance on the NAS (my backups had taken up rather too much space) I turned LMS off. When restarting I was prompted for my MySB login details and the location of my music files. This made me wonder if a file containing these data had gone astray or been overwritten. Anyway, LMS started up without needing a rescan of the music files and operates just fine...or so I thought.

I usually use either Squeezepad or the web interface to use the various Squeezboxes, and rely on the web interface to adjust settings. Now clicking on the 'Settings' link at bottom right of the web interface screen fails to load the Settings screen (actually it seems to load a blank page). Interestingly I can access some of the settings options via Squeezepad.

Any suggestions as to what's happened (and how to fix it)?

Update: I decided that reinstallation was so trivial that I removed the LMS qpkg and reinstalled - I now have the Settings screen again. Still no idea what happened!
