Hello there,
Thanks for confirming! It looks like your site currently has the option GDPR: Wait on consent enabled.
This means that Buttonizer will not load in any scripts until the function enableButtonizer() has been called.
When you disable this option, your button should load in correctly. 😃
You can find this option by going to the Buttonizer WordPress plugin dashboard -> Plugin Settings -> Preferences.
If you would like to keep this option enabled, then you will need to call the function in your cookie consent plugin.
We have an article in our knowledge base with some examples on how to set this up.

Let me know how it goes!
