Hi,
We’ve just had the same issue pop up in our google webmaster tools. I’ve crawled the site using xenu – link sleuth, and cannot see any reference to the the 404 error found by the google crawler.
eg /privacy-policy/function.include-once
I’ve done a fair bit of searching and can’t seem to find the cause of this.
My assumption is that a PHP file is causing an error somewhere which in turn places a link into the page. What I’m confused about is that it should be visible with the link sleuth software…? but the link sleuth is not picking anything.
We did have issues previously with a mysql max packet size but this was fixed.
We currently have 15 errors with this symptom.
Any help or direction here is greatly appreciated.
