 A common issue that users run into after changing the WordPress Address
 and/or Site Address (such as when migrating to a new domain) is that some
 of their links stop working correctly after a site change.

 The most common fix/workaround is to go to the wp-admin > Settings >
 Permalinks page and click "Save" once or twice, which usually does the
 trick.

 Examples of this problem and workaround can be found all over Google:

 https://stackoverflow.com/questions/39514343/wordpress-migration-broken-
 links

 I'm not sure if there's already a ticket for this anywhere, but surely
 there's some way to do this automatically? The view counters on the
 various Stack Exchange questions suggest that it has affected hundreds of
 thousands or even millions of users, so fixing it would be a fantastic QOL
 improvement, especially for non-technical users and users who don't notice
 the broken links until they start getting complaints.

 Would it be possible to automatically flush_rewrite_rules() in the core
 function that handles the address change? I haven't looked into what
 happens when the permalink settings are resaved, but I would imagine that
 it does something similar there.
