[Resolved] Adding product to checkout card

This thread is resolved. Here is a description of the problem and solution.

Problem:
If you're experiencing issues with items disappearing from the cart when added from the category page, but not from the single product page, and this issue resolves when the WPML plugin is deactivated, it might be related to the WordPress memory limit.
Solution:
We recommend following these steps:
1. Increase the WordPress memory limit to at least 128MB. You can do this by adding the following code to your wp-config.php file:

/* Memory Limit */<br />define('WP_MEMORY_LIMIT', '128M');

Add this code above the line that says /* That's all, stop editing! Happy blogging. */.
2. Verify the WordPress memory limit in WPML -> Support to ensure it has been increased.
3. Delete all inactive plugins, flush the cache memory, and update any outdated plugins and themes.

If these steps do not resolve the issue or if the solution seems outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the problem persists, please open a new support ticket at WPML support forum for further assistance.

Background of the issue:
I am trying to add Pokémon products to the checkout cart. The issue occurs when adding items from the category page.

Symptoms:
When items are added from the single product page, they stay in the cart. However, when adding from the category page, only the first item appears briefly before disappearing.

Questions:
Why do items disappear from the cart when added from the category page?
How can I ensure products remain in the cart when added from the category page?

Thank you for sharing the debug information.

1.- I was able to reproduce the issue in the original language, if you deactivate the WPML plugins does the issue persist or disappear?

2.- Please increase the WP memory Limit. Minimum requirements are 128Mb: https://wpml.org/home/minimum-requirements/
You can add this to wp-config.php to increase WP memory:`

/* Memory Limit */
define('WP_MEMORY_LIMIT', '128M');

- Add it above the line /* That's all, stop editing! Happy blogging. */

You can double-check the WordPress memory limit in WPML -> Support

Thank you for your feedback.

Could you create a staging site with a copy of the live site where we can run further tests without affecting the production site? I have set your next message private so you can securely share the access credentials to the staging site.

Looking forward to your message.

Thank you for sharing the information requested.

Important note: The memory limit you mentioned is the PHP memory limit which is different than the WordPress memory limit. The code I provided increases the WordPress memory limit.

I will start running tests in the staging site and I will get back to you as soon as I get more information.
