We have a user that has their cookies enabled, but they are still receiving this error and he has selected one attendee in the drop down box for this event.
I checked your site and I’m seeing the same error message. It appears that your site is getting its content served from a Varnish cache. The Event Espresso checkout pages need to be served dynamically and will not work as expected if served by proxy or from a cache.
To fix, you or your host can set no cache rules for the Event Espresso checkout pages by following this guide:
We have installed WP Fastest Cache have excluded all of event registration and transaction pages.
Our header response code shows the following:
cache-control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0
pragma: no-cache
The header response code you list involves browser side caching. The issue on your site involves maintaining session state which can be affected by server side caching. Here’s a screenshot that outlines the relevant http headers:
If you’re certain that the varnish caching (which isn’t likely controlled by your caching plugin) isn’t causing any issues, then it may be a plugin conflict. Generally whenever we see Varnish caching involved you’ll also see the Nothing in your event queue error, because the session isn’t maintaining state.
