Changing the way WordPress uses permalinks is quite a simple process. You won’t need to install any plugins to do this. To access the settings for permalinks:
Go to the “Settings” section of your WordPress dashboard
One the left side of the dashboard under the “Settings” control, you should see one for “Permalinks.” This is what you should click.
Select the method you want to use and click the “Save Changes” button.
WordPress will automatically make the adjustments to your pages and post. This means you will not have to do anything more if you want the content to be saved a certain way.
