if you change the name of the username, it will change automatic. if not, is because of the browser cache.
I have changed user name and cleared the browser cache and the name does not change
sorry. is true. that is because you can not change the username of wordpress, is like an ID
You have to change it from the database
Don’t do this. It can lead to all sorts of unexpected behaviour and could break your network. Create a new user with the username you want.
Thank you. it works…I have created new user and published book under the new user, and new catalog url has created for that user…
