By default any URL on my website will end with a trailing slash.

So if I publish a post or page, the URL will end with a “/”. But I came across a weird situation where I hit publish but the URL with “/” works but without “/” does not work. And when I clear the cache on the WordPress website. both URLS work. with or without trailing slash.

I was reading this article to see properly configure my rewrite rules.

If anyone can help me understand what this issue could be.
