I'm trying to run two sites on the same droplet, but my new virtual host seems to be having no effect? (Configuration files inside)

I’ve had a website running on my droplet for sometime, and now I’m trying to set up a second on the same droplet but with a new domain name.

I’ve set up the directories, created virtual host files for each site, and enabled both sites.

Currently, every time I visit the new domain, testingdomain.com, I get 301 redirected to domain.com. If I disable the example.com site using a2dissite, then testingdomain.com loads as expected. So it seems as though the virtual host for the original site is overriding the new one when enabled?

Here are my virtual host files:

Main site which works, and which the other domain is redirecting to: http://pastebin.com/3GU7vDhg

New site which always redirects to main site: http://pastebin.com/GHd9tqBp

And my ports.conf file if that might help in any way: http://pastebin.com/hWDC2ZbZ

I’ve spent hours trying to find a solution but with no luck : /

Thanks for any help.
