Answer 1

You don't need to write any .htaccess rules.
There's an option for that in the Admin section called " URL structure. "

Navigate to:

Admin > General settings

Comments

I know this option:  /123/why-do-birds-sing in Admin > General settings but when  I use it, the site doesn't work

Answer 2

Your server must be something different from APACHE.
