WooCommerce Checkout Blocks Integration
-
HCaptcha is not appearing when using the block checkout, and then when an order is placed, a “Bad Signature” error occurs. When you switch to the standard checkout, the captcha appears as it should. Version 5.01 is active, but tested 5.10-RC and it did not fix the issue.
The page I need help with: [log in to see the link]

I tried to reproduce the issue and failed – things are OK on my local site. And I do not see the difference in the HTML markup of your WC Checkout block and mine.
Did you use hCaptcha plugin before v5.0? Had you the same issue?
Could you share the System Info from the plugin admin page?
Thanks.
Hi @kaggdesign , yes, we’d been successfully using hCaptcha with the WC Blocks without issue before this. System info:

### End System Info ###Hi @thunderfrog,
Thank you for the information. I have found the reason. The issue was caused by the “Return to Checkout link” turned on.
I have made a fix. Please try v5.1.0-RC3 and let me know.
@kaggdesign Brilliant! That seems to have done the trick. We might have changed that right before the update to 5.0.1 as well – so just bad timing, but glad it can be fixed for going forward.
Thanks a lot for confirming! Glad to hear that the issue is solved.
If you have a minute and are happy with the plugin/support, we’d really appreciate a quick review on WordPress.org. It helps us a lot and helps other users find the plugin:
