I installed Moodle from cPanel and I saw the plain Moodle. The classic one i think. I wanted to change the theme to Adaptable theme so I downloaded the theme. When I uploaded the theme from plugin. It gave me system check which I don't know how to change it
I installed moodle in to Subdomain. like class.school.com. where school.com is main domain. class. is subdomain.
problem is attached below.
