Hi all
Before the summer holidays, we upgraded our moodle to 3.9 and we also updated to Ubuntu 20.04, with the most recent packages as of July 17 2020.
I noticed several students getting problems of STACK questions not working for their summer homework. Today, on running the healthcheck scripts, I got some errors. I updated plugin to the latest STACK version, and still the same errors. Any pointers would be appreciated:
1. In STACK plugin settings, the highest Maxima version I can set is 5.42.2 but I have Maxima 5.43.2
Health check script output:
