I am using XAMPPS to host PHP files from my machine. I have recently installed XAMPPs but I am unable to start Apache service as port 80 is in use by PID 4 - NT Kernel &
i think the error is here
[pid 5384:tid 240] AH01909: RSA certificate configured for www.example.com:443 does NOT include an ID which matches the server name
or there is another app are using the port 80 try restarting your computer and only opening apache and see what happens
or try on reinstalling apache or using Ampps
