Previously, I had two pages both with content and it was working fine.

I now have a blank page, content page, blank page again, and the final content page with calEXT3. Since adding those blank pages, the calEXT3 module is empty but all others are reporting ok. The default calendar module is still loading the event stream fine, but nothing makes it to the calendar display. I tried reducing to just a single calendar, no help. I also tried going back to the ‘old’ setup with only 2 pages and it still didnt display anything.

I followed these steps from another post, and it didn’t have an effect either:
https://forum.magicmirror.builders/topic/20189/default-calendar-not-loading-events-after-new-mm-update/10?page=1

cd ~/MagicMirror
# restore calendar.js 
git checkout defaultmodules/calendar/calendar.js
git fetch origin pull/4180/head:_fix_304
rm package-lock.json
git switch _fix_304
npm run install-mm
restart MM

Here is my config:
