Website only working on my computer only

Hey all,

I did a website for a friend, as I’m trying to learn the ropes with WordPress. However, just when I thought I had the website up and running (I even checked it on multiple browsers on my computer and it looked fine), my friend tells me that it doesn’t load properly when he visits the site.

I checked it on another computer and he was right, it’s not loading properly. I used HB Theme (High End) and revolution slider. My css that I applied isn’t showing up and neither is the revolution slider or the logo.

Does anyone know what may be causing this?

The website is http://www.cmggroup.net

I promise to reply with how I fixed this once I figure it out.
