Hi irinas2211 ,
I noticed that there was an error in the console log on your site:
I managed to recreate this error when minifying the javascript with Asset Cleanup
.
Luckily, Asset Cleanup has an exclude option right under:
Asset Cleanup -> Settings -> Minify CSS & JS Files -> JavaScript Files Minification
Add these in the "Do not minify the JavaScript files matching the patterns below" box.
If you are using the free version of Buttonizer, add the following script:
wp-content/plugins/buttonizer-multifunctional-button/assets/frontend.min.js
If you are using the premium version, add the following script:
wp-content/plugins/buttonizer-multifunctional-button-premium/assets/frontend__premium_only.js
Let me know if this works for you! 😀
