Can not find 'multisite' extension for TYPO3 version 11

How can i set up multisite in typo 3 version 11.5.8?

The extensions available on the internet are for versions upto 10.

I get the error shown in the diagram below, when I try to install multisite extension from typo3 GUI

Solution

  • Sure, you need this extension?

    TYPO3 is out-of-the-box a multisite-system: https://typo3.org/cms/features/massively-multisite-multilingual

    EXT:multisite

    That extension may solve special requirements for huge multisites. What a "huge multisite" looks like in numbers is written in its doc:

    We have a multisite installation with

    • 600 website (root pages)
    • 3.500 frontend users 400 frontend user groups
    • 60.000 pages
    • 250.000 content elements
    • 3.000 categories
    • 100.000 news
    • 5.000 news categories

    So, for this (or a similar) use-case, the backend can get slower. EXT:multisite changes some behaviors of the backend to speed up operations.

    For a "normal" TYPO3 instance with a couple of sites/rootpages and fewer pages/records, the basics of TYPO3-Core will met all requirements for a multisite.
