Paola, you mentioned the domain wasn't set up properly. Could you be more specific?
I shared the guide with the website guys (see link). But they are unsure what they should work on. Is it this part? 'Here is what you need to ask your hosting company:
When using separate domains: I want to add a parked domain (alias) to my existing domain. My existing domain is “example.com”. I want to park the “example.de” domain.'
I am not sure what is the issue and question here, if it relates to domain setup, the best way to check if it works fine is to disable the WPML plugin and then visit both domains, making sure you can log in to both and see the same content on front.
Let me know how it goes and if there is anything else I can do to help.
as it seems, Paola, noticed that when saving language per domain settings, domains seem to show as not valid.
Usually, this doesn't cause issues with the frontend and working of WPML but could mean there is some specific rule or set for domains that are blocking WPML from confirming the settings or some specific function.
I guess you will need to check for any domain proxy or similar setting, or security booking WPML scripts.
To be fair, I am not 100% sure, since every hosting/domain can have its settings. If you have any issues related to the domain, I suggest testing without WPML, and if any issue with WPML and domains, you can try and test on another hosting/server with some other test domains to confirm it is server/domain settings related. This can easily be done on localhost or any other server with virtual domains, and it should work fine.
