Hi Deirdre,
Thanks for reaching out and thank you for using BoldGrid Post and Page Builder for WordPress!
Permalinks are native to all WordPress sites. If you click the “Edit Post/Page” link on any page you see the Permalink directly below the Page Title section. You can click to “edit” to modify the permalink and save to update the page.
You’d also want to refresh your permalinks after saving your changes. To do so navigate to your WordPress dashboard settings Settings > Permalinks and simply scroll to the bottom and click “Save”.
I hope this helps. Please let us know if you have any other questions for us.
