SiteImprove that we use for our website health has recently flagged https://www.ncmissouri.edu/academics/wp-includes/wlwmanifest.xml as an error “520: Proxy Publisher Failure” on every page. When investigating the issue I found “When your site’s visitors see error 520 in their browser, it means Cloudflare is sending the message because your server returned an empty, unknown, or unexpected response.” Please assist. Thank you!
Interesting, the rest of the site is working ok, no 520 error.
Wonder if it’s removed for security purpose
May I ask if the file is existing and not missing at your server, just in case?
I have reviewed the wp-includes location and the file is included.
Error display page. This site can’t be reached
The webpage at https://www.ncmissouri.edu/academics/wp-includes/wlwmanifest.xml might be temporarily down or it may have moved permanently to a new web address.
