I thought I broke my oEmbed discovery links but I had a more fundamental problem. I had broken fancy permalinks on my nginx configuration for a while and didn’t realize it.

I revisited the Nginx Codex page and did a stare and compare of my configuration and the examples there. I am sure I read that page in the past and my mistake was the “try_files” line.

Here’s what I had for try_files.

location / {
	try_files $uri $uri/ /index.php;

Here’s what that line should have read.

location / {
	try_files $uri $uri/ /index.php?$args;

See the “?$args” part? With that in place the non-post URLs work. The permalinks worked fine but things that were not to a post or page didn’t. Due to my fancy permalink settings my oEmbed discovery links had this format.

https://blog.dembowski.net/wp-json/oembed/1.0/embed?url=urlencoded-data-here and that wasn’t being handled by my nginx configuration.

My plugin worked because I was replacing the fancy URLs with the regular non-fancy “?rest_route” version which nginx passed along to my WordPress installation just fine.


This may have also broken other features as well. I wonder what else I’m missing? I should check all the things. 😉
