Website Error

[hackintoshlover]

Hi,
Thanks for the awesome piece of software.
I finally got it working.
The issue being in file install.sh ln -s $PWD /var/www fails to assign working directory, i changed it to ln -s /home/pi/sandtable /var/www and everything compiled and worked fine.
Upon reboot i ran into an issue wherein sandtable.log says os error: address already in use.
I changed port to 3000 in config and restarted after which i was greeted with the webserver.
In the webserver i am facing couple of troubles:

1. In the lights section if i click on any image i get the error below:
   

2. In the draw section if i click on the image that displays G i get the error below:
   

Have i done something wrong?
Also some the images in the draw section do not generate a preview when clicked.

Hope you guys will help me out with the same.
Thanks.
