Technical requirements

Before installing Joomla or upgrading to a new major version, ensure your hosting meets the technical requirements. This includes the correct PHP version, sufficient database and server resources and appropriate PHP extensions. Requirements differ between Joomla 4, 5 and 6.

  • Function and purpose

    Technical requirements describe the server and software prerequisites for Joomla to operate correctly. They include PHP, MySQL or MariaDB versions, required PHP extensions, web server software and memory or upload limits. Distinguish between minimum and recommended versions.

    Use cases

    • Installation: Verify that your hosting environment supports the versions and modules required by your Joomla version.
    • Migration: Check whether your environment is suitable before upgrading to the next Joomla version.
    • Performance: Also consider recommended settings such as PHP memory limit, maximum upload size or timeouts.

    Important notes

    • Documentation: Detailed requirements for Joomla 4, 5 and 6 can be found in the official manual.
    • Future proof: Use recommended versions when possible for smoother updates.
    • Hosting: Shared hosting may have limitations – consult your provider if needed.
