FAILURE: Nonce check failed.

[AndrewL]

I have had some successful transactions but am also experiencing a few failures with the same error message:

[05/01/2018 12:19 AM] – Payment processing started.
[05/01/2018 12:19 AM] – Triggering hook for addons to process posted data if needed.
[05/01/2018 12:19 AM] – Checking received data.
[05/01/2018 12:19 AM] – FAILURE: Nonce check failed.

Can you advise what would be causing this failure along with suggestions on how to fix it?

Thanks
Andrew

Hi Andrew.

Are you using some caching plugins on your site (like WP Total Cache or similar)? If you are, could you try clearing their cache and see if it helps?

[AndrewL]

I am using a plugin called ‘Cache Enabler’and had previously cleared the cache, however, the failure re-occurred. I’ve checked the plugins’ settings and there is an option to exclude pages from caching. I’ve added the page ID of the page where the Stripe payment block is loaded – would you expect this to alleviate the problem?

[Admin]

If the nonce value goes stale (old value that is cached) then you see this error. Exclude the page containing the Stripe payment button (so the nonce value is always fresh).

Let me know how you go after that.
