Since it’s been a while since I’ve played with Reddit’s open source code I took a few minutes to try and duplicate this problem on a droplet of my own. I was not able to duplicate it but I have an idea of the cause of the issue. You mentioned having installed apache2 before running the install-reddit.sh script. My guess is that this prevented things from being configured properly.
Here are the steps I took to get a reddit install running:
1.) Created a new droplet (I used an 8GB droplet as recommended. A smaller one with swap should work just as well for testing but I would not recommend it for production).
2.) Created a user ‘reddit’
adduser reddit
3.) Added that user to sudoers
adduser reddit sudo
4.) Switched to the new user, changed to their home directory and downloaded the script
cd /home/reddit/;
su reddit;
wget https://raw.github.com/reddit/reddit/master/install-reddit.sh;
5.) Then I ran the script with sudo, as the reddit user.
sudo ./install-reddit.sh
Once the script completed, I created an entry in the /etc/hosts file on my local computer (on Windows this file is in C:\Windows\system32\drivers\etc\ while on Linux/Mac it is /etc/hosts. The entry I created pointed the name reddit.local to my droplet’s IP address. Then I could browse to reddit.local and see:

So, I would recommend doing a rebuild of your droplet with a fresh install of Ubuntu 14.04 and re-try the installation.
