I have installed XAMPP on my pc and I change all port from \'443\' to \'4433\' and \'80\' to \'8080\' but when I start Apache it say me that port \'80\' is already use but A
I had same problem.
Then when you use xampp control panel, sometime you have to face same problem as I was.
Go to xampp control panel. Using config button open configuration of control pannel. Then click service and port setting and under appache setting you can change your main port 80 to 8080.
