What I like to do is open two browser windows so that I can look at the frontend and the backend of the website.
1. Admin View
2. Website View
After you login, On the dashboard there are only 11 buttons.
On the left, these correspond with the pages on your website:
On the right, these are global settings:
Styles and Fonts
Click the Home button at the bottom left.
Then click to examine the section ‘Top Photo + Text Overlay + Button’
Here you can upload (click the icon of the arrow pointing up) a new photo for the background and change the Title ‘Therapy with Lisa’
Click Save in the bottom right corner.
