Using https://www.drlinkcheck.com/ to scan our site we found that there are a number of links from within the Download Manager plugin which are broken. Looks like they are missing from the package.
To name some:
/wp-content/plugins/download-manager/assets/file-type-icons/dmg.svg
/wp-content/plugins/download-manager/assets/file-type-icons/gz.svg
/wp-content/plugins/download-manager/assets/file-type-icons/bz2.svg
/wp-content/plugins/download-manager/assets/file-type-icons/msi.svg
I’m quite sure I have already reported the last one over a year ago, picked up by Ryte free scan. The broken links hurts page ranks from what I can tell, fixing them should be quite important.
