Also encountering the same issue.

I was able to resolve it by simply restarting apache.
Update:
After I encountered the issue again on another site I realized that the commonality was PHP7. I haven’t dug into the issue enough to check the cause of the conflict, but that appears to be it for me.
Ya was not working for me either – using php7.
Managed to get it to work thanks to another user pointing out there was a deprecated function in the code. To fix it:
Replacing line 13 of services.php from
if (ereg('[A-Z]+',$arg))
to
if (preg_match('/[A-Z]+/i', $arg))
(Sorry for the redundancy – hope this will be fixed in the next release)
There are some extra steps to make it work with PHP 7. Please check https://wordpress.org/support/topic/deprecated-function-used/ for more details.
