Quick post that explains how to fix the error, “The authorization header is missing”. This error may be found under “recommended improvements” in the WordPress Site Health tool (located under the WP menu ▸ Tools ▸ Site Health).

When running a Site Health check, the “authorization header” warning happens when you’ve upgraded WordPress (to version 5.6 or better) and have Permalinks enabled, but the site’s .htaccess rules have not been updated with the latest. This DigWP tutorial explains what’s happening and shows how to fix the error easily with a few clicks.

Easily hands down the most common thing that I find myself explaining to WordPress users is how to troubleshoot WordPress in order to find the cause of some issue. And it makes sense if you think about it. WordPress and all of its plugins and themes are made of code. And code is a complex thing. The more code you add to a site, the more likely it is for bugs and issues to happen. And when they do, it can be confusing and frustrating to the average user.

Something I did not know about when working with Custom Post Types and Custom Taxonomies. Normally when checking if a regular WP Post belongs to a specific category, we can use the WordPress function in_category(). But that does not work with Custom Post Types. To check if a CPT belongs to a specific term in a Custom Taxonomy, use has_term() instead.

People often ask me whether it is safe to run plugins that are not tested with the latest version of WordPress. And it’s a good question, because software in general is something that you want to keep current and updated with all the latest. For WordPress plugins however, there are many plugins that simply don’t need to be updated with each new version of WordPress.
