I’ve set a custom permalink structure to have /blog/ included in the permalinks for posts. This is the custom permalink declaration in the WordPress settings page: /blog/%postname%/

The issue I’m facing is that the 404 page template is not loading if the custom permalink structure is active. Everything works fine if using the /%postname%/ permalink structure or not using permalinks at all.

Any thoughts?  
Thanks,  
Marto

Have you tested with another theme to find out if Sage is the culprit or not?

Regardless, I suggest you install [Debug Bar – WordPress plugin | WordPress.org](https://wordpress.org/plugins/debug-bar/) or something similar that lets you see the request and which rewrite rule is being matched by your URL. That should help you tracking down any underlying issue.

Possibly also add [https://wordpress.org/plugins/debug-bar-rewrite-rules/](https://wordpress.org/plugins/debug-bar-rewrite-rules/) to further ease debugging rewrite rules if needed.

Hello folbert,  
I have tested with twentytwenty theme and in that case it works.

Any idea here? this is actually happening on any Sage9 theme that I’ve tried when I try to use a custom permalink structure for posts.

Here’s the debug info from the Debug Bar.

Sorry, I misread your first post and thought you got 404 on a valid blog-url. The plugins I suggested ant that you screenshotted probably doesnt help at all.

FWIW, I have Sage9-sites with custom permalink structure, including ”blog” where the 404-template loads without any issues.

I dont have any other suggestion than to do some code diving to, for example, see if WP is loading another template or maybe change the content of your 404-tpl to just a harcoded text to make sure it is not loaded.
