I am seeing this popup error which on one of my events which says:
An error has occurred:
The stored data for session ee_ssn_85315366c7589dba327e280b7629432a failed to pass a hash check and therefore appears to be invalid.
EE_Session – _retrieve_session_data – 705

Hi there,

I’ve just had a look over some of your events and didn’t see the notice you mentioned, is this happening on a specific event?

The above can happen if you have an open session from opening a registration checkout page and then attempting to start another, you can check if that’s the case by first visiting the registration-cancelled page on your site to clear your current session.

Hi there,

Do you have any caching plugins on the site?

Both you and I are getting the same ee_ssn_ value, which isn’t expected and likely means the response has been cached. Clear any caching you have enabled on the site and retest.

Also, your site currently has WP_DEBUG enabled which is why that error message is being shown, if you edit your wp-config.php file you’ll have something like:

define( 'WP_DEBUG', true );

Change that to be:

define( 'WP_DEBUG', false );

Is the error removed from that page?
