Upon trying to check out

An error has occurred:
The stored data for session ee_ssn_e44ef5d1c97c7ebf704e4aac947adcbc failed to pass a hash check and therefore appears to be invalid.

Hi there,

Is this happening on every checkout instance?

If you clear the session by navigating to the {domain.com}/registration-cancelled/ page then retest does it work then?

doesn’t change the problem. the error occurs across all events. WP updated last night and didn’t change the situation either.

Hi there,

It sounds like there’s some caching happening on the server side, where the checkout page has a stale cache so the hash check is given an old stale session hash.

If your site is hosted on Godaddy Managed Hosting, there is a way to deactivate their built-in caching. You follow this guide:
