Cannot work out why a bunch of urls are giving a 404 error

[Niamh2]

I have used the Crawl Diagnostic reports to greatly reduce the number of 404 errors but there is a bunch of 16 urls that were all published on the same date and have the same referrer url but  I cannot see the woood for trees as to what is causing the error.

**The 404 error links have the structure:**http://www.domainname.com/category/thiscategory/page/thiscategory/this-is-a-post

The referrer structure is:

http://www.domainname.com/category/thiscategory/page/2/

Any suggestions as to how to unravel this would be appreciated.

Hi

I put it on the back burner for a while. This morning i had another go and I think it was caused by shortcodes for accordion style links put in a long time ago by someone else. I've taken the shortcode out and will see if things have improved on the next report.

Thank you for responding. I will follow that lead.

As the error happended on the same day I think if I find one I will have all sorted.

Hard to say without looking at the actual page, but it looks like http://www.domainname.com/category/thiscategory/page/2/ is probably a paginated category page (when you're in a category, and looking through older posts). There is probably a relative link somewhere on the page ( vs ), that is causing the link to be malformed. So take a look at the category template, and replace any relative paths on those pages.
