URL=referer no longer working?

I recently noticed my use of ?URL=referer stopped working.

I am an IMac and use the latest version of Chrome.

All my pages that use your validation service stopped working.  I had <a href="http://validator.w3.org/check?uri=referer">HTML Check</a> on hundreds of pages.

Now when I click the link it goes to the top of my website only???

My site is HTTP:..lilesnet.com/home/index.htm

I LOVE your service and want to keep my pages up to date but alas, now I have to manually type in each and every pages I want to check!

HELP PLEASE
