I am using EE4 v.4.9.2.p and WordPress 4.5.3 and when people try to buy tickets for events they get one of two error messages:
The following errors have occurred:
An invalid registration was received.
A valid Primary Registration for this Transaction could not be found.
or
An error has occurred:
Your form data could not be applied to any valid registrations.
These errors pop up either after they have entered registrant info and clicked on the go to payment button or when they have clicked through the payment selection page to the payment gateway. Some transactions do go through but it seems to be a 50/50 chance if it’ll work.
I am also using the WP Users addon, which I have disabled because the point at which people are forced to login seems to disrupt the ticket process. Even with the addon disabled, these error messages still pop up. I am using W3 Total Cache and have disabled caching on all EE pages per the online instructions. We have GoDaddy hosting but it’s not managed wordpress. I’m not sure what server caching GoDaddy is using.
Because the site is already live, I need to figure out why some transactions won’t go through to the payment page with these errors.
The site is millburnshorthillschamber.org

Do you have database caching enabled with W3 Total cache? If you go to the W3 Total Cache settings and disable every caching option (without actually disabling the plugin) does the error still occur?

I turned off database caching which reduced the number of times I got the error but I did still get it. After turning off all caching I haven’t gotten it yet but it doesn’t happen with every transaction.

You’ll need to verify that Event Espresso’s pages are served dynamically and not served from a cache. Otherwise you’ll continue to see those errors.
