Welcome to the Q&A Forum

Hey there, This is Michael on the Moz Help Team! Sorry to hear about the trouble here. To see the source of those errors, you’ll need to export your full Crawl Diagnostics CSV, which you can do by clicking the "Email CSV" button at the bottom of the issues overview. Once the report generates, it will be emailed to you and you will want to open it up in something like Excel. In the first column, perform a search for the URL of the page you are looking for. When you find the correct row, look in the column labeled Referrer (column AM). This tells you the referral URL of the page where our crawlers first found the target URL. You can then visit this URL to find where we linked to that page. Hope that helps!
