I followed it from the start and I finished it as well, it was the same issue and that was why I downloaded the final project from github to test and see where my mistake was. But it is the same issue. Actually I tried installing Vagrant from the beginning but it did not work out due to some issues with my laptop.
I followed it and I fully understand the tutorial from A-Z…even with the problem it keeps displaying, I still continue to work on one of my personal projects just to get the full understanding of it. This is another reader who makes the same complain right here…Novice to Ninja book {error} while using XAMPP - #13 by TomB
