Hello,
First of all thanks for choosing our Theme, we are glad to be you in the WoodMart WordPress family :-)
.
I have visited your website but there are no social icons added on the website. Please provide with the screenshot of the specific area where you want to change the icons type to check it myself and help you out accordingly.
You can find header settings under WoodMart >> Header Builder.
