# Platform Settings Chamilo has an extensive configuration system with settings organized into categories. The full set of categories below mirrors the **Configuration settings** page in the admin panel — and the underlying `SettingsCurrentFixtures.php` in the source code, which is the source of truth for variable names, titles, and descriptions. Access platform settings from the administration panel by clicking **Configuration settings**. ![The platform settings page showing configuration categories organized by functional area](/files/pV5Ud2oytQBybuTtP84W) ## All categories There are **39 configuration categories** in total, listed alphabetically below.

and managed through the web interface * Some settings are **URL-locked** in multi-URL setups (their value applies platform-wide and cannot be overridden per URL - see `access_url_locked` and `access_url_changeable` columns in the `settings` table); others (most) can be overridden per access URL * Changes take effect immediately (no server restart required), although your user session might be keeping some of them in memory. If changes don't reflect immediately, logout and login to flush your session. * Some settings have dependencies — changing one may affect the behaviour of others * Variable names shown on each page (e.g. `2fa_enable`) match the row in the `settings` database table (`variable` column) and the keys used in overrides (`config/settings_overrides.yaml`) where applicable. For more information, check [Configurations](https://github.com/chamilo/chamilo-lms/wiki/Configurations) on our wiki. ## Tips * **Document your settings** — Keep a record of non-default settings and why you changed them * **Change one thing at a time** — When troubleshooting, modify one setting at a time so you can identify the effect * **Test in a staging environment** — For significant setting changes, test on a staging server first --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
