Hi. Excuse my english.
I have two grid courses. Both courses have the same definition, but in
one the popup windows work correctly and in the other they don't. I changed theme and it's the same.
Everything is fully upgraded.
Debian 10
Moodle 3.7.1+ (Build: 20190725)
Format_grid 3.7.0.3 (2019052502)
PHP 7.3.4-2
Regards!
