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

Problem:
You want to translate H5P activities on your WordPress site using the WPML plugin, but you cannot find how to do this because the H5P plugin is not compatible with WPML.
Solution:
Although the H5P plugin is not directly compatible with WPML, if your H5P activities are registered as a custom post type or custom taxonomy, you might still be able to translate them. Here’s how you can adjust the WPML settings:
1. For Custom Post Types:
Go to: WPML → Settings → Post Types Translation and set the relevant post type to Translatable.
2. For Custom Taxonomies:
Go to: WPML → Settings → Taxonomies Translation and set the taxonomy to Translatable.
Please note that even with these settings, full compatibility is not guaranteed due to the lack of official integration from the plugin author.

If this solution does not resolve your issue or seems outdated, we recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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 you still need assistance, please open a new support ticket at WPML support forum.

Thank you for contacting WPML support.

The H5P plugin is not compatible with WPML. Based on our internal records, our team reached out to the plugin author in the past, but unfortunately, they never responded, and no integration was developed.

However, if your H5P activities are registered as a custom post type or custom taxonomy, you may still be able to translate them by adjusting the WPML settings:

1. For Custom Post Types

Go to:
WPML → Settings → Post Types Translation
and set the relevant post type to Translatable.

More details:

2. For Custom Taxonomies

Go to:
WPML → Settings → Taxonomies Translation
and set the taxonomy to Translatable.

Please note that even with these settings, full compatibility is not guaranteed due to the lack of official integration from the plugin author.
