Reported for: WPML Multilingual CMS 4.6.7
Overview of the issue
If you are using WPML and experiencing 404 errors on secondary language child pages, it may be related to an identified issue with the url_to_postid() function.
Workaround
Our developers are aware of this situation and working in a better url_to_postid() integration.
In the meantime, please avoid using parent pages that start with the current language URL code.
If you have child page like http://domain.com/fr/freelances/freelancing-avec-statut/ that leads to a 404 error, change the slug of “freelances” parent post to something that does not start with “fr“, e.g. “our-freelances“
