Cannot create lessons from course edit page with WPML active

[cena]

See: 5302767-zen

When attempting to create a lesson from the course edit page, clicking on 'Save to Edit' leads to loading, then removal of that lesson from the module block:

Disabling WPML and going back to same course edit page now shows all the lessons I previously tried to create for this course:

These lessons also appear in the Lessons->All list.

I can now create a new lesson correctly.

Re-enabling WPML and going back to same course list now shows ALL lessons created in Sensei:

and now cannot create new lessons via 'Save and Edit'.

Maybe related:

Disabling the Avada-child theme didn't seem to have an effect after disabling WPML, until I tried editing lessons again from course edit page after re-enabling WPML, and that led to this error:

Disabling Avada Core & Avada Builder plugins removed it, and I was able to renable Avada-child without encountering the error again.

However, I also re-enabled Core & Builder afterwards and also haven't been able to duplicate error since.

EDIT: I was able to get a copy of WPML and install it on my test site. Once registered, I had access to their forums and found this related issue:

https://wpml.org/errata/cannot-add-a-quiz-question-in-sensei-when-wpml-is-active/

Although marked as 'resolved', they later say it's not, and to use this plugin for the interim:

WPML-Sensei-compatibility-master.zip

Installing this results in the following error when attempting to create a new course:

Fatal error: Uncaught Error: Too few arguments to function WPML_Sensei_Compatibility::wpml_save_post_trid_value_filter(), 2 passed in /wordpress/core/6.0.1/wp-includes/class-wp-hook.php on line 307 and exactly 3 expected

In addition, my course edit page (in block editor) says: Your site doesn’t include support for the "sensei-lms/button-take-course" block. You can leave this block intact, convert its content to a Custom HTML block, or remove it entirely. This is using the Storefront theme.

So the above plugin, while not our problem, seems to be targeting non-block-based sites, which are no longer supported by Sensei.

Just noting for future reference.

Note: user ended up cancelling Sensei after a month of all of us (her and HEs) to get this worked out; there doesn't seem to be a good workaround here. :(
