If the URL is not saving, from Settings>301 Redirects, search for the original url. Usually, if the URL is not saving it is because it already exists.

If the URL does not exist:
  1. In WordPress, navigate to Settings>301 Redirects
  2. Attempt to change the URL's to match the criteria of which page should redirect to the other
  3. Save changes and check in browser if it's working
  4. If it is still redirecting to the old page, or not redirecting, attempt to completely remove the redirect and see if function still persists
If redirect persists after the above steps, Click Chat with Support and reference this article. Please be prepared to share the following information with Support:
  • URL to the WordPress site
  • Original URL
  • URL that the Original URL should be resolving on
If a site has an SSL cert and 301 redirects are failing, check Settings > General and look at Wordpress Address (URL) and Site Address (URL) and make sure both are set to the HTTPS version of the URL.
