Okay managed to SSH to my droplet and upon doing so I get a list of instructions. ....

To finish installing Wordpress, navigate to your droplet's IP: http://178.xx.xx.xxx and use credentials from below.

When I type in the ip address I get.....

Forbidden

You don't have permission to access / on this server.

Why on earth am I getting this????

Am unsure about the next bit as well....

Make sure to specify hostname from DO panel to your droplet before creating it (for example: 'blog.mydomain.com' or 'myblog.com')

I believe I did this when I set up the droplet a few weeks ago:
droplet name: dev.mysite.com
hostname: www.mysite.com

No idea what this is all about, haven't got this far:
Server will also respond to its IP address, so if you finish installation from http://IP then
you will need to change hostname from Wordpress Settings later (from http://IP to http://hostname)

So frustrating!!
