Hello,
If you want to enable the social icon of the theme please follow the following steps.
1. Go to Dashboard =>Appearance => Menu
2. Create a menu and assign the location as social menu.
3. Add custom links to the menu, the custom links are the links of your social icon eg. Facebook.com/myprofile
4. Got to Dashboard => Appearance => Widgets
5. On your left you can see widget named “education hub social”. Drag and drop the widget in any preferred widget area. If you want it as the theme demo, add it on “footer widget 1”.
I hope the instructions were clear and it helped.
Best regards.
