I just pushed an emergency update out of LonelyCache. It appears that GC HQ changed the transaction level security from 1.1 to 1.2 and that broke the authentication/authorization handshaking between LonelyCache and Geocaching.com. Unfortunately this came at a time when I was making other changes to LonelyCache that I needed to clean up and perform some database schema changes. Fortunately I was mostly done so it wasn't a disaster
Enjoy,
Russell
