Thank you for checking in and providing an update on the error you’re experiencing. I understand how interruptions like this can be limiting.
Could you please share a screenshot of the error, as well as a link to the other thread where you noticed it unresolved? This will help us further troubleshoot and analyze the trend.
We would also appreciate it if you could share your system status report from WooCommerce > Status > Get system report > Copy for support, using Pastebin or Gist.github.com.
Thank you for sharing the screenshot — that makes things clearer. From what I can see, the error you’re getting is coming from your WordPress.com account while trying to add a payment method, not directly from the WooCommerce Tax plugin itself.
Since this is tied to your account and billing setup, the best next step would be to reach out directly to the WordPress.com support team so they can look into your account configuration: https://wordpress.com/sites?help-center=wapuu
It’s been a while since we heard back from you for this reason we are closing this thread.
If WooCommerce Shipping has been useful for your store and you appreciate the support you’ve received, we’d truly appreciate it if you could leave us a quick review here:
