Sorry for being slow in responding – I tried to post a reply yesterday but got an error msg from your database.
Anyway – thanks, unfortunately, it did not work. I’ve just had time for a quick test, over the weekend I might have more time to dig into this and maybe contact the WPML support, too. I can’t say I understand exactly how things are supposed to look even when they’re working, so to speak. All I can see it that the custom field of that custom post type does not get picked up by the WPML translation editor, and when I “force it” to, it ignores it somehow.
Maybe this has something to do with it: https://wpml.org/faq/how-to-translate-custom-types/ i.e. you have to “do the right thing” in the plugin somehow.
So I’ll have to get back to you with more information and/or questions in a few days (or more). If you come up with something please let me know :).
Thanks for the quick response.
