Embeds endpoint not working after switching permalinks

[pbearne]

I just set the permalinks back to the default /?p=1219 format and the iframes is still pointing to the /eb/embed/ URL so we get the fall through

I don't know if we can catch this but I post this just in case someone can work out a way.

That's because oEmbed responses ( the <iframe> embed code) are cached. WordPress doesn't know if an embed code is for your own site and therefore can't change it. Besides that, none of your pretty permalinks will work when you switch back to ugly permalinks. That is not limited to embeds.

Since oEmbed responses are cached, invalid responses won't suddenly begin to work. You'd need to clear the oEmbed cache during development, e.g. by using WP_Embed::delete_oembed_caches() or by deleting the rows manually from postmeta tables.

If you change your permalink structure back to the default, all of your permalinks break, not just the /embed endpoint. I don't think anyone can expect them to continue to work in this situation.

It does appear, though, that canonical redirects don't take endpoints into consideration, which means if you change your permalink structure to something else (except the default), the endpoint (such as /embed) gets stripped from the redirect. This probably needs its own ticket.
