I am experiencing an intermittent issue with the Event Espresso plugin when trying to add events to the cart. This problem does not occur every time, but it happens sporadically, causing an inconsistent user experience.

Here is a video demonstrating the problem for better understanding:

The problem is happening on website. Here is the conference page where the events are listed. You need to register on the website to see the page.

This is an *URGENT ISSUE* for us since some users are not able to register.

Thank you for your help in advance.

Hi there,

This type of intermittent behavior is almost always due to applying server caching on pages that should not be cached. eCommerce code and pages should not be cached so that the data can be accurate during and after the registration occurs.

I can see on your conference page and on the event details page that caching is happening. Here are the response headers:

– Conference page:
– Event Details page:

The way to fix that is disable caching on ecommerce pages. Here is more info:

Does that help?
