    I've had my site go down and was told by Kinsta support:

    The error occurs because the array_values() function in /wp-content/plugins/meta-box-aio/vendor/meta-box/meta-box-builder/src/Helpers/FieldKeys.php is receiving null instead of an array.

    It took my site down right after I installed a plugin (Theme My Login). Not sure if that was the cause but I've had to rename the plugin in my plugins folder in order to get back into admin. I looked for pending updates to AIO but I don't see anything.

    I was able to get the site up by renaming the meta-box-builder folder within AIO and updating the Field Keys file:

    public static function all(): array {
    if ( self::$all_keys !== null ) {
        return self::$all_keys;
    }
    self::build();
    if ( self::$keys_by_type === null ) {
        return [];
    }
    self::$all_keys = array_values( array_unique( array_merge( ...array_values( self::$keys_by_type ) ) ) );
    return self::$all_keys;
}
