Error: Could not validate nonce

Hi

Apologies for the trouble.
This issue should be resolved with our next plugin update which we are currently preparing. We are aiming for sometime next week, but it depends on a few factors.
In any case, you can download a package that includes our fix for this issue from here:
https://drive.google.com/file/d/1PZuqz_jakapp_0hHeXXAQl-CRlEIPWZQ/
Please give it a try and let us know if other reports about this come up.
Thanks!

Kind regards,
Niklas

Thank you! I’ve installed the plugin and we will see if it works.

I installed it this morning and no issues as of now. I will report back if anything arises.

We will publish a new update asap and hope that will solve the problem. The update is scheduled for the next few days

Checking back through my error log, I started getting the error again. It registered an error on: July 14, July 16, July 20
[20-Jul-2021 16:59:32 UTC] PHP Fatal error: Uncaught WooCommerce\PayPalCommerce\Button\Exception\RuntimeException: Could not validate nonce. /wp-content/plugins/woocommerce-paypal-payments/modules/ppcp-button/src/Endpoint/class-requestdata.php:50

I look forward to the update.

Thanks,

Same error occurred on July 24 and July 26. I’m running version 1.3.2

This issue should be fixed with the most recent version 1.4.0 which was released yesterday.
Can you please install the new version and let us know if any issues remain?
Thanks!

Kind regards,
Niklas

Upgraded to 1.4.0 yesterday afternoon EST (7/28/21).

Received back to back nonce errors, probably the same customer trying the order twice at 3:33:42 UTC

Hi @graniteindustries,

The last update resolved one potential cause for this error, but some isolated reports remain and we are investigating how else it could be triggered.
Since we can’t reproduce it, it’s not quite clear to us yet, but we are working on it.
If you create a support ticket with us as described in the link below, then we could maybe provide a test version to see if it resolves the error for you.

Thanks!

My plugin completely stopped taking orders last week. Even for a $1.00 product, it was unable to process the transaction. I’ve moved on to try another plugin.

Hello

Today I was informed that the cause of the “Could not validate nonce” message, could be traced back to the “Guest checkout” and “Account creation” settings (can be found under “Accounts and Privacy).
It seems that this issue occurs when you have the guest user checkout option (first checkbox) disabled and enabled the “register an account in the checkout” and either account username or password generation or both (either of the two lowest checkboxes).

We are working on getting this resolved, but it might give you an option on how to get this resolved by adjusting these settings

Once we have a fix in place, we will update this thread as well.

Kind regards,
Joost
