Problem: The client was experiencing multiple critical issues with Custom Post Type (CPT) translations and permalink generation in WPML across different language subdomains. The specific problems included permalinks only working in the language they were last saved, incorrect redirects for CPT archive pages, an error message when editing CPT posts in Russian, and domain mapping issues with the Russian subdomain.
Solution: We identified that the client was incorrectly setting the slug for their CPTs, which affected the translatability of archive slugs. We recommended setting the rewrite array correctly in the
register_post_type()
function, specifically ensuring that the 'slug' key is correctly defined to make the archive slug translatable. For example:
rewrite' => array('slug' => 'book'),
This adjustment allows the slug to be translated according to WPML's standard procedures. We also suggested checking our documentation on translating slugs for custom post type archives for further guidance: Translating Slugs for Custom Post Type Archives
If this solution does not fully resolve the issues or seems outdated, we recommend opening a new support ticket. Additionally, we highly advise checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
