Problem: The client has two custom post types (CPTs): 'hotels' and 'congresses'. Each hotel is associated with one or more conferences using the 'congress' taxonomy assigned to the 'hotels' CPT. In the default language (English), the client assigns or removes conferences using this taxonomy. However, these assignments are not automatically reflected in the translations, requiring the use of the troubleshooting tool to synchronize post taxonomies. Solution: We advised the client to change the settings for the 'congress' taxonomy to be translatable and only show translated items. This can be done by navigating to WPML > Settings > Taxonomies Translation and setting 'Congresses (congress)' to 'Translatable - only show translated items'. After adjusting these settings, the client should translate these taxonomies under WPML > Taxonomy Translation. Additionally, we suggested testing the 'use translation if available or fallback to default language' option, although it might lead to unexpected results and translating the categories might be a safer approach.
