Hello, I’m having the same problem. Standard works no prob, but express gives me the JSON.parse error. I disabled all plugins except woocommerce, UPS, and PayPal for WooCommerce and still got the error. I even tried a different template with all plugins disabled (except for the previous) and got the error. Any help would be appreciated. I enabled and checked the log, but couldn’t find much useful information. Please let me know how I can fix this. Thank you and any help is appreciated.
Thank you for the quick response. That is great news. I’ll definitely check out the dev branch. Is the dev branch ready for a live site or should I wait till the official version is released before going live. I appreciate you helping me on this matter and thanks for a great plugin.
