Appendix: Configuration Settings

This appendix on configuration settings aims to provide you with a list of parameters that can be modified in config.php and the impact each value will have.

We will first examine config.php and explore what types of parameters are supported by Moodle. After providing this overview, we will look at two types of configuration settings:

• Administration settings: These variables are available via the Site administration menu but can be locked with values specified in config.php.
• System settings: We distinguish between default and supplementary configuration values. The former will have been created by the installer and are mostly required for Moodle to function; the latter are parameters that change various Moodle behaviors.
