Error on website says:
Exception - Call to undefined function gradingform_guide_get_fontawesome_icon_map()
Has anybody came across this one?
This happened when I tried to migrate moodle folder from an older Ubuntu server that has 3.6.5 moodle to the new server that has Ubuntu 20.04 and moodle 3.9.x. May be I have to try migrating everything (moodle, DB, moodledata) first and then see if the same error occurs. Please advise.
Also please advise the right course of actions to migrate Moodle 3.6.5 / Ubuntu 18.04 to Moodle 3.9.x / Ubuntu 20.04.
