Suddenly this site doesn't work for me. The start command is in French, and my location has moved from Raymond, MS to somewhere off the west coast of Africa! Pressing start does not do anything. Clicking in the typing box and pressing enter does not work either. I am getting warnings even on my home page. For example:

Warning: Error in parsing value for 'background-image'. Declaration dropped.

There are MANY more similar warnings as well.

If you have any step by step instructions as to how I can STOP all of these errors and enjoy key hero typing test again, I will thank you in advance!

You can ignore (CSS) errors in the Tools > Error Console.
Those errors are only useful if you develop websites and want to check the HTML/CSS and JavaScript code for errors.
Most errors are code for other browsers like IE or browsers on other platforms or just typos or the result of bad coding.
