hi there ppl :)

I need some help, have been trying to solve it and google around but no luck...
So I have linux server with virtualbox working fine, also installed phpvirtualbox following mainly https://wiki.archlinux.org/index.php/PhpVirtualBox which succeeded.

I'm running Arch, here some info on my system and the config:

Linux fatzo 4.9.8-1-ARCH #1 SMP PREEMPT Mon Feb 6 12:59:40 CET 2017 x86_64 GNU/Linux
php 7.1.1-1
apache 2.4.25-1
virtualbox 5.1.14-1
phpvirtualbox 5.0_5-1

info on my config:

Now to my error :) when i go to the login page my browser loads i enter the user name and password (admin/admin) then it gives the error below:

There was an error obtaining the list of registered virtual machines from VirtualBox. Make sure vboxwebsrv is running and that the settings in config.php are correct.

The list of virtual machines will not begin auto-refreshing again until this page is reloaded.
HTTP error: 500 Internal Server Error

DetailsreadyState: "4"
responseText: ""

apache logs show this:

how to get this fixed, searched around for a while but can't find a solution, please give me some pointers if you have ideas or the solution thank you in advance :)
