I have 404 errors but can't find where these links are?

[JackMurphy]

The 4xx report had 0 errors, and then on the recent crawl it found over 200. They are all variations on real URLs e.g.:

Real URL:

http://www.bullseyeuk.com/10-up-deluxe-literature-holder.html

404 Error URL:

http://www.bullseyeuk.com/10-up-deluxe-literature-holder.html ��

None of them are linked to the root domain and I can't find where they are coming from.

Any ideas?

Thanks

Jack

I have found out where they're from! I exported the crawl report and saw under the referring column where the links come from. It's in a directory which I haven't blocked in the robots.txt, it's in the process of being changed so hopefully when the website is next crawled it won't find these URLs in the first place.
