apache starts but stops right away - apache

Question

For a while now I can't start apache.
(I don't have skype running)
I have tried googling it but no help.
I tried reinstaling, same thing. Tried easyphp, same thing happens to it too.
When I start it it says it started, but few seconds later it says it has stoped, and shows an error
20:39:59 [Apache] Attempting to start Apache service...

Hope someone knows what the problem is

Answer 1

It looks like you have ssl improperly configured for one of your domains (www.example.com). Try commenting out Include (path)/(to)/httpd-ssl.conf include line and LoadModule ssl_module modules/mod_ssl.so in your httpd.conf file.
If the commenting out of the ssl config works, it may be that the SSL port (443) is in use on your machine. Uncomment the above, then in httpd-ssl.conf, try changing line(s) Listen 443 to an alternative (not-in-use) port number, i.e. Listen 49199.
At the command line, you can use netstat -aon to see what ports are currently in use on your machine.
