so i'm following this tutorial... and i installed xampp, and it was working all right, i went to the hosts file under the system32/drives/etc, and added the following at the bottom...
127.0.0.1 www.example.com # For browser access
127.0.0.1 mail.example.com # For email access
127.0.0.1 example.com # For mercury mail server
and apache was working fine... and when i went on example.com, it was the same as localhost...
but then it told me to configure the htppd.conf file under apache, and change servername from localhost:80 to www.example.com:80
then apache doesn't work. i don't know what they want to do with all those configurations (i'm setting up a website with zen cart), and i don't know if those configurations are necessary. but if they are, apache isn't working, and i know that's necessary. your help would be much appreciated.
