I’m using shortcodes to display registration box on my event pages.
People are getting a “There is Nothing In Your Shopping Cart” error message.
It works on a couple of computers but for the majority of users it’s broken.
I’ve tried different versions of the shortcode
with quotes
[ESPRESSO_TICKET_SELECTOR event_id=’3081′]
without quotes
[ESPRESSO_TICKET_SELECTOR event_id=3081]
Here is an example

Important Info box
WordPress Version:
4.1
PHP Version:
5.4.28
MySQL Version:

I took a screenshot but I don’t see where I can attach an image?

Hi, could you setup no cache rules for your caching plugin?

An error has occurred:
The [ESPRESSO_CALENDAR] shortcode has not been properly registered or the corresponding addon/module is not active for some reason. Either fix/remove the shortcode from the post, or activate the addon/module the shortcode is associated with.

Hi Kris,
Are you using the [ESPRESSO_CALENDAR] shortcode within the page? If so do you have the EE4 Calendar Addon plugin installed and activated?
The first step is to exclude the EE pages from caching following the link Lorenzo provided above. That will not likely fix the error you have just posted, but you will find many strange problems whilst caching the dynamic EE pages.

No – I’m just using the shortcode from the “event” itself so people can select a ticket.
[ESPRESSO_TICKET_SELECTOR event_id=’3081?]
I’ve updated the caching and am still having issues.

Still getting this error:
Nothing in your Event Queue
You need to select at least one event before you can proceed with the registration process.

Is this something that could possibly be fixed if I purchased a support token?

Hi, caching still appears to be active as registration from a single event page also has the same issue with the empty queue messaging.
Did you clear the cache for W3 total after setting up the exclusion rules?

I did clear all of the pages via W3. Is there a setting I’m missing?

Now it’s saying:

When you view the source code of a cached page you see something like this – http://take.ms/x9OY5
Your pages are still cached/caching which is why you get the latest issue.
Did you follow the steps here:
https://eventespresso.com/wiki/setup-nocache-exclusion-rules-event-espresso/#w3tc
Then purge (delete) the cache?

I followed the steps and purged the cache:
this is in the Never cache these pages
wp-.*\.php
index\.php
/events/
/registration-checkout/
/transactions/
/thank-you/
/registration-cancelled/

It’s still not working.
Is there another setting in the plugin that you know of that might need to be changed?

Hi, could you try clearing the cache and then turning off the caching features and deactivate and remove W3 total cache?
Does it then work?
If so, please try WP Super Cache instead.

Hi Kris,
You’ll need to also disable caching for pages where you’re using the Ticket selector shortcode. For example, on this page:
http://www.caringdoc.com/programs/event-espresso-test-page/
If you view the source of the test page, you’ll see that it’s still being cached by W3 total cache.

I turned off page caching and I’m still getting the error

Hi,
That is strange since the cache has been turned off. Could you login to your WP site using an SFTP or FTP client (e.g. FileZilla, Cyberduck, Transmit) and go to this location:
/wp-content
You may see several cache_ related files there. If you do, could you delete them?

Hi Kris,
Is object caching enabled? If so can you try turning off object caching?

Could you try now? I turned off everything and deleted the “cache” folder.
Thanks for all of your help.

Hi Kris,
I checked again and a little more deeper and the response headers are showing that the webpages on your site are being served via Varnish caching. Here’s a screenshot that shows the response headers:
https://www.evernote.com/shard/s4/sh/2dc011db-05b2-423d-8d81-8e2b00cc90b9/bd24ad0ffe0eb596207001d7cf158d30
Varnish caching is usually configured at the server level (not from a plugin). This means you can contact your host to see what your options are to allow Event Espresso pages to be served dynamically, not from a cache.
