C3 Micro-Cloud 4.7.x and 4.8.x
These instructions are valid for C3 Micro-Cloud installations with version 4.0.x up to 4.8.x. C3 Micro-Cloud 5.0 and superior use a different Moodle installation strategy.
You need to access the C3 Micro-Cloud using a SSH client like putty. Then following instructions:
Go to /usr/share/moodle
Execute the following command to fix this issue:
sudo -u www-data php admin/cli/purge_caches.php
If you still get an error after executing this command, you might need to perform a manual cache reset. Please use the following command:
sudo rm -fr /var/lib/moodle/cache
C3 Micro-Cloud 5.0 and superior
Cleaning the Moodle cache is different in this version. Since Moodle runs under docker, you need to perform the following command:
sudo rm -rf /data/docker/thirdparty/moodle41/volumes/moodle/bitnami/moodledata/cache
