Live version not working when the local version is?...
On the bottom right you'll see three blocks of text. The above buttons are meant to have on hover messages to let you know what they are and they are meant to switch the content below, of which all three are showing.
Link removed due to fix...
I am posting here as I do not know what the problem is whereas everything is working on my local but when I uploaded to my they do not change or have their over effects although you can see the tab switches edit the url.
