Webpage displays "It Works!" message

I am trying to solve the problem on my friend's laptop. Whenever she accesses one particular site, the page only displays "It Works!" message. I've checked the internet, yes, it's connected, and this only occurs on her laptop. The site can be loaded just fine on other computers.

I would guess that some browser setting or an add-on (adblock, flashblock, scriptblock, etc.) is preventing the site from working.

Download and install a different browser to her laptop, and try to reach the site with that one, and see if the site displays normally.
