Link

For the past few years I've been using a {{YYYY}}/{{M}}/{{slug}} format for my links. I'm reconsidering not having that leading 0 for the month. What will happen to old posts if I change it to {{YYYY}}/{{MM}}/{{slug}}?

I have two posts with slugs. After being published, their URLs have "-2" added right after the slug. I have checked the slugs of each post and confirmed that they are not identical. This leads me to believe that there might be another reason for the addition of "-2" in the URLs. Here is one of the post has a slug "bionic" but it's URL is displayed as being "bionic-2": https://kuoyihs.in/bionic-2.

For example, a post title (and file name) is foo. Can the post URL be mysite.com/bar?
