Hi yasir4452 ,
Thanks for reaching out to us!
Buttonizer has 2 versions right now. The WordPress version and the Standalone version ( the one on app.buttonizer.pro ).
Unfortunately, both of these currently don't work together. We will release an update in the future that will fix this.
For now, if you would like to only use the WordPress version, you can simply remove the Buttonizer integration code.
It should look like this:
<!-- Buttonizer -->
<!-- End Buttonizer -->
If you would like to continue using the Standalone version, you can deactivate the Buttonizer WordPress plugin.
Please let us know if removing the other works for you! 😄
