My Apache Ports are set to:
80 and 443
Looking at the XAMPP control panel a few hours later, I noticed the Ports had changed to:
05 and 59895
Same problem was answered in this post by one of XAMPP developers. Assuming this is real (quote):
In short, that is normal. Apache listens for and accepts requests on ports 80 and 443 but it does not service requests on those ports. When you or others connect to your servers, they will be handled by other connections usually using high ports. The control panel just looks for all ports associated with a module. It is just picking up those client ports and the box to show all the ports is just not big enough to show them all.
