One custom tab is missed on translated products pages

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

Problem:

You are experiencing an issue where the 'Scientific facts' tab is missing for the LV language on all product pages, despite being translated using the Product Tabs for WooCommerce (Free) plugin.

Solution:

This problem arises due to a compatibility conflict with the Product Tabs for WooCommerce plugin, which is not officially compatible with WPML. We resolved this on a staging site by modifying the code. You can apply the following change in the woocommerce-product-tabs/src/Product_Tabs.php file at line 90:

$key = apply_filters( 'wpml_object_id', $key, 'woo_product_tab' );

Please verify if this resolves the issue on your site.

If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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 issue persists, please open a new support ticket.

kasparsV	Background of the issue: I added new custom tabs for products using the Product Tabs for WooCommerce (Free) plugin. All new tabs are translated. The issue is with the 'Scientific facts' tab, which is missing for the LV language. When I open the 'Edit translation' link, I see both the original and translated texts for this tab. This problem occurs on all products. Here is a link to a page where the issue can be seen: hidden link Symptoms: The 'Scientific facts' tab is missing for the LV language on all product pages, despite being translated. Questions: Why is the 'Scientific facts' tab missing for the LV language? How can I ensure all tabs are displayed correctly on translated product pages?

Bigul WPML Supporter since 01/2013 Languages: English (English ) Timezone: Europe/Vienna (GMT+02:00)	Hello, As mentioned earlier, this issue is due to a compatibility conflict with the Product Tabs for WooCommerce plugin, which is currently not included in our list of officially compatible plugins. That said, we were able to achieve the expected results on your staging site by adding the following code in the woocommerce-product-tabs/src/Product_Tabs.php file at line 90. $key = apply_filters( 'wpml_object_id', $key, 'woo_product_tab' ); Please check the site now and let us know your feedback.

Bigul WPML Supporter since 01/2013 Languages: English (English ) Timezone: Europe/Vienna (GMT+02:00)	Hello, Thank you for the updates. Could you please clarify whether the entire Custom Tab is missing for the Latvian Products or just its content? It would be helpful if you could share a couple of screenshots so we can better understand the issue. -- Thanks! Bigul

kasparsV	Custom tab is present for both languages. Content translation is missed for LV. It was there but now its missed.
