We noticed that the W3TC Page Cache prevents media items from being moved into the Trash.

Steps to reproduce the problem:
#1
Activate media trash in wp-config.php:
define( ‘MEDIA_TRASH’, true ); // Media Trash
define( ‘EMPTY_TRASH_DAYS’, ’31’ ); // Trash Days

#2
Turn on the W3TC Page Cache.
It doesn’t matter which page cache method is used.

#3
In Media Library, try to move any item into Trash by clicking on the Trash link or checking the checkbox in front of the item and then select Move to Trash from Drop Down and click on the Apply button.

After the page reloads, the item is still in the Media Library, and at the same time, the message says “Media file moved to the Trash. Undo”

Checking the Trash shows that the item is not there. Clicking on the Undo in the message returns the error “Error in restoring the item from Trash.”.

#4
If we a) Deactivate media trash in wp-config.php OR b) Turn Off W3TC Page Cache, moving Media items into the trash works again.

Tested on:
————
Lastest WP: v6.5.5
Lastest W3TC: v2.7.3
Plugins: all plugins deactivated except W3TC
Theme: Tested on multiple themes, including Twenty*
————–

We need Trash functionality, and we can’t risk elevating the client’s permissions to modify the configuration (turn on/of Page Cache) of the W3TC on its own.

What can we do?

Can you please take a look and let us know what and how to fix the problem?

Looking forward to hearing from you.

Kind regards.
