Welcome to the Q&A Forum

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, On the MOZ bar there are a couple of links.  I understand most of it, but what is an RDs?? PA - page Authority
DA - domain authority
Lks - links (to this page)
RDs - ??
