This is a Wordpress tutorial on how to change the Logo & Site title in WordPress.
Step 1:
Go to your Admin. On the right panel, select “Appearance”, then “Customize”.
Step 2:
From there, select “Site Identity”.
Step 3:
This is where you can view and edit your site title, tagline, and site icon. You can also edit your browser tabs, bookmark bars, and mobile apps. You can upload your site icon/logo by clicking on the “Select site icon” option. Click on “Published” to save the changes you’ve made.
*Some may have “Header & Navigation Settings” where you can add your logo.
ADDITIONAL WAY:
Step 4:
You may or may not have this option, depending on your theme. Go to your theme, then select “Theme Options” from the drop down menu. In this case, my theme is named “Extra” from Divi.
Step 5:
In the “General” tab, you’ll find where you can upload your logo. You can also upload a separate Favicon here.
Again, some themes don't have this option. If you don't, you can use the default way that I showed earlier.
Hope this helps!
