50,000 4xx errors listed in MOZ report :(

[Skips]

HI,    I've just had a look at a customers MOZ report and discovered nearly 50,000 errors listed!!  The site is a non dynamic, non database driven site so where these have come from is beyond me.

Example - (Both links open in a new window)
LIVE PAGE - http://lunnonwaste.com/licenses/Heatherland-Limited-H&S-Policy-Document-JAN-15.pdf 
NON EXISTANT PAGE - http://lunnonwaste.com/licenses/licenses/Heatherland-Limited-H&S-Policy-Document-JAN-15.pdf - if you hover over any links you'll see they're ALL ......./licenses/licenses/..........  which doesn't exist!

It's the file system that seems to be the problem - .........../licenses/licenses/...........  and this gets added onto  (............./licenses/licenses/licenses/licenses/.............. , up to the 50,000 page errors LOL  The problem is self replicating.

It's very odd and not something I've ever seen before, NON of these 'extra' pages are listed on the server, so where are they coming from?

Any suggestions or help would be gratefully appreciated

Hi Michael

Making a simple research "site:lunnonwaste.com" you have indexed 51 pages on Google. Which is Ok, the problem with the 404 pages probably is created in your server side for some of the scripts on it. As you mentioned this is a simple website, made it with html and css, no with any CMS, that is the reason I think is a script in your server.

The solution find the script and fix the error, meanwhile you can redirect the 404 pages to your Homepage
