Hello,
Could you please, upload xstore/js/etheme-scripts.min.js on your web-site and check again. File you may find on next link -> https://dropmefiles.com/hmk1n
We uploaded the file on our demo also and it seems now the problem was fixed but we have deep caching so it is cached for customers with old version files that’s why we sent you a file to check from your side.
P.S. you should have the latest version of theme/core 8.3/4.3 -> https://xstore.8theme.com/update-history/
Regards
