Hello, this is for the social media buttons on the top.
Go to Appearance –> Menus
Look at ‘select a menu to edit’ –> click ‘Social’
Look at ‘custom links’ and click the drop down arrow.
In the URL box, insert your social media URL (eg: facebook.com/xxxxxx)
In the Link Text, insert the name of the social media platform (eg: Facebook)
Then click ‘Add to Menu’, then ‘Save Menu’.
Repeat the above for other social media platforms.
Took me a while to figure it out too! I hope it works for you!
