Hey kvishnunambiar !
Thanks for reaching out! First of all, best wishes for 2024 🥂
I've checked your site and found the issue. Buttonizer instances are bound to domains where they are allowed to load. Since your staging domain is not whitelisted, Buttonizer does not load on your site. You can read more about this here: https://community.buttonizer.pro/knowledgebase/919-buttonizer-locked-to-domains
With our agency plan, you are able to allow Buttonizer to load on multiple domains if you really need it: https://community.buttonizer.pro/knowledgebase/2050-adding-secondary-domains-agency
I checked your main website and saw that Buttonizer works as it should, so if you don't really need the widgets on your staging website, you don't need to worry about that message 🙂
Let me know if this helps 🙂
