We’ve fixed this bug with MySQL 5.7 (`Unknown database type json requested`) in Mautic 3.2, to be released on **November 30**. The fix will only apply to **new** installations and to installations that don’t have `db_server_version` in their `app/config/local.php` yet (this is the case if you haven’t changed the default configuration in Mautic’s UI before). Otherwise you have to change the version in `app/config/local.php` yourself, as mentioned in [Mautic 3.1.2 installed - Plugins are not available](https://forum.mautic.org/t/mautic-3-1-2-installed-plugins-are-not-available/17003/3).

Apologies for the inconvenience and thanks for reporting this!
