Thank you for contacting WooCommerce support.

I understand you are facing two issues with payments and order status.
Let’s focus on the payment issue in this thread.
If the second issue still appears after that, we can revisit it later on.

Since the issue occurs with all payment methods, including cash on delivery, I need more details to investigate further. Please share your site’s System Status Report. You can paste it into Pastebin, then share the link here.

Once I have more information, I will be in a better position to assist you further.

Best regards.
