However, I notice that when I go to settings/permalinks and change
FROM: Custom Structure, https://mysite.com/%category%/%postname%/
TO: Plain, https://mysite.com/?p=123

instead of my custom 404 template, it displays a file not found from 404.shtml in the public_html directory.

This behavior is repeatable because when I revert back to the custom structure, it returns to the customized 404 template.

How does changing the permalink setting as described determines which 404 file is executed?

You can still access: example.com/category/news-999/company.

The alias of the top-level category, “news,” can be changed to any letter and still be accessible, for example:

• example.com/category/aaaaaaaa/company
• example.com/category/2345678/company

Even with incorrect parent category aliases, it is still accessible. Why does this happen? This should be unreasonable, right?

can I use whatever permalink structure I want if I use yoast or do you reccomend one permalink structure in particular? And why? Now the structure of my permalink is mywebsite.com/%category%/%postname%/ and I am planning to change it to mywebsite.com/isola-di-govinda/%postname%/

I have a website that includes normal pages, blog posts, and a store. I want to change the permalink structure only to the blog posts. The blog post has to be mywebsite.com/isola-di-govinda/%postname%. How to do it with no plugin?

For the other pages, the structure has to be mywebsite.com/%postname%/ (it can be changed inside the dashboard, I know). For normal page is currently mywebsite.com/%category%/%postname%/

I am looking forward to hearing from you.

I initially discovered this issue while rewriting and redirecting video media attachment pages within the ‘/video/’ structure. The findings are as follows:

• URLs containing ‘/video/’ stop AMP conversions for video content.
• URLs containing ‘/image/’ do not have any issues.
• Changing the base URL to anything other than ‘/video/’, such as ‘/vid/’, solves the issue.

Here is the code snippet that demonstrates the issue:

add_filter('attachment_link', function($link, $post_id) {
	$post = get_post($post_id);

	if ($post->post_type == 'attachment') {
		$mime = get_post_mime_type($post_id);

		if (strpos($mime, 'video') !== false) {
			$link = home_url('/video/' . $post->post_name . '/');
		} elseif (strpos($mime, 'image') !== false) {
			$link = home_url('/image/' . $post->post_name . '/');
		}
	}

	return $link;
}, 10, 2);

Further testing revealed that simply setting the permalink structure (from the WordPress menu, for all posts) to ‘/video/%postname%/’ halts all AMP conversions.

I am currently using Version 2.5.4, the latest available version.
