@gravnetic As noted in your other thread (https://ww.wp.xz.cn/support/topic/hosted-form-fields-are-not-working-self-hosted-works-fine/), there’s issues with CloudFlare’s Rocket Loader as it will compile our plugin’s JavaScript with the rest of the site’s JavaScript files, and this process changes when our JavaScript is executed, resulting in the error you’ve posted above. We’ve attempted to opt-out of Rocket Loader in the past (via https://plugins.trac.ww.wp.xz.cn/browser/woocommerce-securesubmit-gateway/trunk/classes/class-wc-gateway-securesubmit.php#L82), but it doesn’t have any effect. While we’re investigating options, disabling Rocket Loader (at least for checkout) is the only current option that is known to work.
@gravnetic I took a look at your checkout, and it seems you have CloudFlare’s Rocket Loader enabled. We’ve seen some compatibility issues with our plugin and that offering.
