So I extracted the piwik.zip file into my site and went to mywebsite.com - This website is for sale! - mywebsite Resources and Information.

500 Server Error
A misconfiguration on the server caused a hiccup. Check the server logs, fix the problem, then try again.
What do I do?
I followed this video tutorial: How To Easily Install and Setup PIWIK Analytics - Step by Step
