Nothing works when set to auto populate :-/

WeatherMapper
Automatically generate weathermaps from a LibreNMS database using WeatherMapper Link

I have done this several times now to the letter - and nothing generates. So I added a few devices/links - and when I try to load the page:
http://usmlbnetmon.percepta.com/plugins/Weathermap/output/mymap.html

My regular dashboard pops up. I am betting my bottom dollar that I am missing something highly obvious - but thought I would throw this up here anyway.
