Ubuntu 14.04.1 multiple SSL certificates error - apache

Question

I have setup 2 websites on my Ubuntu web server and am having some trouble with getting two SSL certificates to work correctly. I did get one working on it's own at first, however, now I can't restart Apache successfully.
Error when trying to restart Apache
* Restarting web server apache2
* The apache2 configtest failed.
Output of config test was:
AH00526: Syntax error on line 3 of /etc/apache2/sites-enabled/website1.conf:
ServerName takes one argument, The hostname and port of the server
Action 'configtest' failed.
Output of /etc/apache2/ports.conf
# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in

Any help or verification of my config would be greatly appreciated. Thanks in advance.
