Moz Reporting Incorrect 404's

[EwanFisher]

Hi Guys

SEOMoz is telling me that we have 191 404 errors f.

I have checked this with several other crawlers and this not the case.

For example, http://www.opticalexpress.co.uk/eyecare/corporate-savings.html%0D%0A2027

But correct links its http://www.opticalexpress.co.uk/eyecare/corporate-savings.html which is fine...

We have no record of these links so why is it appending these characters at the end of the URL  which is causing the 404's....

If I click on your "correct" link I'm getting a 404 page. The %0d%0a code represents carriage-return/line feed. Is google webmaster tools reporting any problems?

It looks like there's a problem with the way that URLs are being encoded. It looks like the urls are correct on your site (/800512027 instead of /%0D%0A2027).

If Moz is the only place showing these problems (and the URLs look find when I've looked at the site) then I'd report this as a problem to the SEOmoz help folk.
