Requirements
What the server needs before you install Micro CMS.
Micro CMS does not need a large hosting stack, but a few PHP and filesystem features are important.
PHP
Use PHP 8.1 or newer. The installer and Site Health will report required PHP features that are missing.
ZIP support
PHP ZipArchive is required for browser-based ZIP installation of Resource Packs and Extensions, and for full backup workflows.
Writable folders
The folders identified by the installer for site data and Media must be writable by the PHP user. Do not make the whole site world-writable to work around a permission problem.
Optional PHP features
PHP DOM is required if you want to allow SVG uploads. Micro CMS checks SVG files before accepting them and leaves SVG support unavailable when the required PHP feature is missing.
Database options
Standalone sites can use the built-in database option and can later move supported data to MySQL or MariaDB through the provided migration screen.
