Hi CPA ,
Welcome to the forums! 🥳
I took a look at your site and it seems that your theme is adding a background image into Buttonizer.
You can fix this by adding this custom CSS:
background: none !important;
Regarding the whatsapp and facebook button,
you can simply choose the WhatsApp and Facebook button actions in your button settings.
For WhatsApp, fill in your phone number. When a user clicks on this button, they'll be sent to your WhatsApp profile.
For Facebook, fill in your Facebook username. When a user clicks on this button, they'll be sent to your Facebook profile.
