I'm new to Moodle. Recently, I have installed Moodle (ver 3.6.1+) and some selected extra plugins on my Synology NAS. Execution of cron has been set as well.
However, Moodle cron returned the following warning message: "Cannot load Zend OPcache - it was already loaded".
In fact, I have very limited knowledge on Linux. Could anyone help me solve this problem? Thank you.
