[Resolved] Multiple subpages in French cannot be accessed anymore

Problem:
The client reported that after adding local landing pages with a Custom Post Type (CPT), some pages in French were not accessible anymore, showing 404 errors. The issue seemed related to URL conflicts between the CPT and existing pages.
Solution:
We recommended the client to first try re-saving permalinks in Settings → Permalinks to flush rewrite rules and to temporarily disable the Yoast SEO Premium to test if redirection rules were interfering. After further investigation, it was found that the issue was due to a conflict where the same slug was used for both a CPT and a page. The solution involved ensuring unique slugs for CPTs and pages. We advised checking and editing slugs at WPML > Settings > Post Types Translation.
