php 8.4 incompatibility

    On fedora (php 8.4), I get this php warning:

    Deprecated: Function mysqli_ping() is deprecated since 8.4, because the reconnect feature has been removed in PHP 8.2 and this function is now redundant in /var/www/html/wordpress/wp-content/plugins/mainwp/class/class-mainwp-db-base.php on line 262

    Bypassing the ping-function in class-mainwp-db-base.php on line 262 (by just making it return true), works fine:

    public static function ping( $link ) {
    return true;
    if ( self::use_mysqli() ) { // NOSONAR - required.
        return \mysqli_ping( $link );
    } else {
        return \mysql_ping( $link );
    }
}

    Hey @liedekef

    Thanks for pointing this out to us.

    I’ve reproduced the PHP Warning. We will have it fixed in the next MainWP Dashboard release.

    Just a note that the code doesn’t actually use mysqli_ping() unless there’s a compatible setup, which are older PHP versions.
    This Warning is mostly informative and doesn’t imply functional issues.

    The fix for this was included in version 5.4.0.20 of the MainWP Dashboard plugin, released on August 19, 2025.

    Thanks for reporting this to us.
