The error is displayed because the URL has added the symbol ; at the end.
If we remove the symbol ; the URL it works normally.
This is for all the .pdf files I have on my site. About a hundred 404 crawl errors have occurred from this site. (http://aparser.docme.ru/results/paperzz/18w24/week-eldocz.txt)
Does anyone know what this site is?
I also noticed that Website contains too many sites.
How do I fix these 404 crawl errors?
