I would assume it either IS or IS NOT compatible - no in-between.

Again, can you confirm whether the Inline Commenting is compatible with WPML there are problems that I need to sort out, and I don't want to waste my or others' time if it is not compatible.

Also simply changing the inline comment ID doesn't actually work, it only works UNTIL the next time the original post is updated in the WPML Translation editor where the original shortcode overwrites the inline comment ID in translated posts.

Please wait a bit. We'll get in touch with you shortly.

I have had WPML waiting to try to help resolve the situation and would like to get back to them with the correct information so we can get our site functioning correctly.

Thank you

Response from WPML:

Hello there,

It looks like an compatibility issue, can you reach out to the plugin authors and ask if this inline comment feature supports multilingual, we can translate the questions using the shortcode, but it still doesn't appear so we will need to know if it works with multilingual website

You can also ask them to join our compatibility program to create compatibility with WPML: https://wpml.org/documentation/support/go-global-program/

So can you confirm that all aspects of the Inline Comments are 100% compatible with WPML (I don't want to tell them it is without confirmation first)

If you generate a unique ID it should work fine. 

When the new post is created by the WPML, here should be used the WordPress native functions, so you should not have any issues. If you see some, just edit the post and save it without making any changes, so it should work fine.

Does the ID need to be assigned by the wpdiscuz plugin? 

OR can I assign it a random (unique) ID?

If this is possible then I can translate the shortcode and update the ID while translating the rest of the post.

The problem is to edit the Shortcode I need to register the Shorcode to an XML config file with WPML. When doing this it creates a problem with saving translations with WPML. The Advanced Translation Editor gets stuck while saving.

(When the shortcode XML registration is removed everything works fine again)

I consulted them regarding this and they have asked me to confirm with wpdiscuz if the Inline commenting (and therefore translation of the shortcodes) is compatible with WPML?

yes, please try it and let us know how it works. 

So each inline comment will have a unique ID and comments are based individually on each language - correct?
