Changing url on article won’t redirect

It should not redirect automatically. Users would end up with a pretty crazy amount of redirects as they changed page-names over time. & what would we expect to happen when they changed the page name/url back to what it was previously?

You can use a plugin to add a redirect at the php-level or add redirects in your server configuration.

I like to use Safe Redirect Manager: https://en-ca.wordpress.org/plugins/safe-redirect-manager/

Redirection is another popular option: https://en-ca.wordpress.org/plugins/redirection/

& here’s a link to some more plugins which could help: https://en-ca.wordpress.org/plugins/search/redirect/

Best wishes,
