Hello,

You can go to Dashboard > Theme Settings > Footer > there check if you have made the Footer with the Widgets or HTML Block.

If you have made the Footer with HTML Block then you can edit the Footer there with the Page Builder plugin active on your Site with the option available there: https://i.snipboard.io/sI0wWm.jpg

Or if you have made the Footer with Widgets > then you need to go to Dashboard > Appearance > Widgets > there you can find the Footer widget areas from Footer Column 1 to Footer Column 5 > there you can add or edit the Widgets added related to the Footer on your Site: https://i.snipboard.io/fNieHM.jpg
