Phpvirtualbox fix on 5.1 using 5.0 Rumi, October 12, 2017October 12, 2017 I was able to get v5.0-5 working with vbox 5.1 by commenting out the version check line and replacing it with a static value in the endpoints/api.php file: // $response['data']['responseData']['phpvboxver'] = @constant('PHPVBOX_VER'); $response['data']['responseData']['phpvboxver'] = "5.1-0"; Src: https://sourceforge.net/p/phpvirtualbox/discussion/general/thread/565b7f31/ Administrations Configurations (Linux) Virtualbox Phpvirtualboxvirtualbox
