When I save a post wordpress adds a number at the end of postname in the slug or permalink.
For example I have setup my site to use
after saving or updating a post my URL becomes
This number could be any digit from 1 2 3 4 I dont have many posts yet so I am not sure and all my post slugs have one common last word in the permalink xyz-OneCommonWord abc-OneCommonWord or def-OneCommonWord. These become xyz-OneCommonWord abc-OneCommonWord-2 or def-OneCommonWord-3
I read that there is some problem using category and postname together so I choose Month and Name format but the problem is persistent. I update the posts and its the same URL with a digit again.
How I can stop this behavior? Is this a well known issue?
