Server Environment Checks
The server environment page is a really useful page for checking the health of your server software and database. It can be accessed through:
Or you can add
/admin/environment.php to your base URL.
It will confirm that your database and PHP version is correct for the given Moodle version and that all expected PHP settings and extensions are enabled. It will also tell if you need to do anything to your database e.g. Antelope to Barracuda conversion, or utf8 to utf8mb4 conversion.
Also, you can a moodle version e.g. 3.5 upwards if you are on Moodle 3.4.x and determine if the Moodle upgrade will require any underlying server changes e.g. PHP/database version upgrades.
An important step when planning your upgrade process.
