Change the Site Icon
The site icon (also known as the favicon) is the small icon that shows up in the browser tabs when viewing your website. If you don't have a site icon set, you might see the Digital Church logo show up by default. If you'd like to use your own site icon, follow the instructions below.
In the Global Options for your website, you can change the site icon (also called a favicon).
Access the Global Options
First, hover over the settings icon in the admin toolbar and then click on Global Options.
Navigate to the Site Icon Panel
Navigate to Header > Logo > Site Icon and set the image there. You should use a square PNG file that is 512x512 pixels.
