[Resolved] Product hover image not working in second language

Problem:
The client was experiencing an issue where hovering over a product image on the English version of their site did not change the image, while it worked fine on the Danish version.

Solution:
We recommended the client to ensure that the secondary images used for the hover effect are properly synchronized between the default language (Danish) and the translation (English).

1. Make a small edit to the product in the default language and update it.
2. Then, update the translation so that the gallery images carry over.

For the production site, we advised the following steps:
1. Go to WPML->Settings->Custom Fields Translation and ensure that the "Multilingual Content Setup" meta box is visible on the post edit screen.
2. Edit any product in the default language, scroll to the bottom, show system fields, and set the following to copy:

_product_image_gallery

has_variation_gallery

3. Make a small edit and click "update" to ensure that the gallery images are synchronized.

We also addressed a performance issue by recommending an increase in the WordPress memory limit. The client was advised to add the following code to their wp-config.php file:

define( 'WP_MEMORY_LIMIT', '256M' );

define( 'WP_MAX_MEMORY_LIMIT', '512M' );
