JRI / Geocaching Map Enhancements

The same for me, Chrome Version 90.0.4430.93 (Official Build) (64-bit), issue:

You can work around the problem by installing the GClh script as well. Among other things, this script replaces the new header on the geocaching pages with an old one. That was necessary because we couldn't keep up with the adjustments so quickly. A positive side effect: GME is running again.
