Problem: The client is experiencing a fatal error when activating the Turkish translation on their website using WPML String Translation. The error indicates missing interface bindings in the WPML core, specifically when the WP-Parsidate plugin is active. This issue causes the website to crash only when switching to the Turkish language. Solution: We investigated the issue by creating a copy of the client's website. We identified that the conflict was with the WP-Parsidate plugin. Deactivating the WP-Parsidate plugin resolved the fatal error, and the Turkish language started to function correctly on the site.
