Hi @madeincosmos,
Thank you very much for your help.

Problem was with the plugin UpStroke: WooCommerce One Click Upsells.

Solution is add this script to site.

<script>
// fix UpStroke: WooCommerce One Click Upsells (WooFunnels)
if (!String.prototype.startsWith) {
  String.prototype.startsWith = function(searchString, position) {
    position = position || 0;
    return this.indexOf(searchString, position) === position;
  };
}
</script>

Hi @madeincosmos,
are you sure you used IE11. Your screenshot looks more like Edge.

Screenshot our browser: https://prnt.sc/pkfu4d

I ran SqPaymentForm.isSupportedBrowser() in console and our browser is supported. But none of the credit card fields are clickable. Plugin don’t load iframes into the fields.
