IE=Edge,chrome=1 Error Appears Mistaken

Hello,

On several of my pages, I’m getting the following error:

Error: X-UA-Compatible HTTP header must have the value IE=edge, was IE=Edge,chrome=1.

But the meta tag that is on the page (http://freelen.org <http://freelen.org/>) is this:
<meta http-equiv="X-UA-Compatible" content="IE=edge" />

There’s no “,chrome=1” anywhere on the page.

Is there something wrong with the validator or have I made a mistake?  It’s certainly possible that it’s the later!

Thanks!
