I cannot figure out how to edit the footer on our home page. I just need to change our physical address.
With a link to your website, I could have taken a look. It depends entirely on which theme you’re currently using, and there are thousands of themes out there.
But in most cases, the content in the footer of your site usually consists of widgets. If so, you can visit: Appearance > Widgets, then click on the widget that contains the text you want to edit.
Or, open the Customizer, then select Widgets from the menu on the left, and finally, select the widget that contains the text you want to edit. The advantage to using the Customizer is that you’ll be able to see the effects of your changes in the real-time Preview on the right.
This video tutorial, part of the WordPress 101 course, will show you how to edit widgets:
Hope this helps!
