Frequently asked questions
How do I know if my learning platform uses Moodle 4.3?
The checker looks for the MoodleSession cookie, M.cfg JavaScript configuration and /theme/ or /pluginfile.php/ assets. Moodle usually hides its version.
Is it dangerous to keep using Moodle 4.3 after support ends?
Without support, new vulnerabilities are not officially fixed, so the risk grows over time. It does not mean the site is compromised today.
How do I update Moodle?
Moodle upgrades should follow the official path, run from the command line when possible, and be tested with your plugins and theme.
