apache launching

[saragiuli]

Hi everybody,
i'm not sure this is the right place to ask my question but i'm a new forum member and i hop eyou'll forgive me.
this is the problem: i just installed xampp 5.6.15-1 version and i had some problem with the launch of apache. i had to change the port 80 in 8080 but now the control panel shows this:
Error: Apache shutdown unexpectedly.
12:19:47 [Apache] This may be due to a blocked port, missing dependencies,
12:19:47 [Apache] improper privileges, a crash, or a shutdown by another method.
12:19:47 [Apache] Press the Logs button to view error logs and check
12:19:47 [Apache] the Windows Event Viewer for more clues
12:19:47 [Apache] If you need more help, copy and post this
12:19:47 [Apache] entire log window on the forums

in the logs apache error i found this:
[ssl:warn] [pid 8948:tid 496] AH01909: www.example.com:443:0 server certificate does NOT include an ID which matches the server name
[ssl:warn] [pid 8948:tid 496] AH01909: www.example.com:443:0 server certificate does NOT include an ID which matches the server name

I did't change the ssl port that now is 443
Any idea of what this could be?
I'm new in programming andi'm not so expert..
my operating system is windows 10.
Thank you
