Hello @abhishekdayal,
Thank you for reaching out!
Error showing – There are no payment methods available. This may be an error on our side. Please contact us if you need any help placing your order.
Could you please attach a copy of your site’s System Status report? You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support” (after you scroll down a bit)”. Once done, please paste it here in your reply or via a text-sharing service like https://gist.github.com/.
It would be great if you could also attach a few screenshots that illustrate the issue.
If you don’t already have a screenshot service installed, here are a few free options:
Look forward to hearing back from you.
Problem Solved. It was due to woocommerce block issues with payment gateways. I edited the checkout page replacing blocks with shortcodes.
