Hello, I'm going to try and be as specific as possible concerning this weird issue, but I'd rather not say specific info about the site unless you think it's pertinent. So to summarize, we have a website that's owned by a company that is a division of another company. For reference, we'll say that: OURSITE.com is owned by COMPANY1 which is owned by AGENCY1 This morning, we got about 7,000 new errors in MOZ only (these errors are not in Search Console) for URLs with the company name or the agency name at the end of the url. So, let's say one post is: OURSITE.com/the-article/ This morning we have an error in MOZ for URLs OURSITE.com/the-article/COMPANY1 OURSITE.com/the-article/AGENCY1 x 7000+ articles we have created. Every single post ever created is now an error in MOZ because of these two URL additions that seem to come out of nowhere. These URLs are not in our Sitemaps, they are not in Google... They simply don't exist and yet MOZ created an an error with them. Unless they exist and I don't see them. Obviously there's a link to each company and agency site on the site in the about us section, but that's it.
