Error Message appears after clicking Register button

After clicking the register button for any of the events on my website an error pop up appears. It doesn’t actually stop the registration process but not something I want my clients to see. I have updated the plugin and flushed my sites cache but the error message still appears. How do I make this go away?

The error message can be found here after clicking the register button –

An error has occurred:
The stored data for session ee_ssn_2cb7a8ce2f993b37cb5825bbcf33cb7d failed to pass a hash check and therefore appears to be invalid.

What you could do is configure you caching plugin (or contact your host) and ask them to exclude caching any pages with /events/ in the URL. If those pages are served from a cache, then that could cause other problems, like allow registration for an event that’s recently closed for registration.
