Help! Installing Moodle but I'm getting "fatal error: $CFG->dataroot not configured properly"

I’m trying to install Moodle, but all I’m getting when I go on my site (learn.foundationstone.epizy.com) is “fatal error: $CFG->dataroot not configured properly”. I checked the other discussions on this same problem, but found nothing that worked. Any help would be appreciated; thanks!

maybe this is the problem
