Improve this question I posted in my website with title: sample1, the permalink was changed to https://samplewebsite.com/sample1. Then when I add another post with title: sample2, the permalink was still https://samplewebsite.com/sample1, the previous post has gone. When I try to look at it, the post ID of the previous post was the same in the new post. It doesn't change automatically.
