PHP 7.2 recommended. PHP 5.6 still works.
PHP 8.2 works, if you have SQlite, CURL and ZipArchive installed (not a default in PHP 8)
FTP or file manager access to install
You should have a PHP configuration with SQLite. Many key-value files are now implemented with SQLite. If, for some reason, SQLite is not installed with your PHP installation, add this line to configration.php:
$swDbaHandler = 'db4';
This will use the Berkeley DB.
The default installation of MAMP has SQLite, but not Berkeley DB.
