Problem: When using WPML on a multilingual site with subdomains for different languages, switching from a German page to an English page results in a 404 error if the English translation is not available. This issue does not occur when switching from German to Estonian or from English to German. Solution: We recommend checking the settings for 'Link to home of language for missing translations' in WPML. If this setting is correct and the issue persists, consider the following steps: 1. Delete the category (e.g., Griechenland) for the English language, which will then redirect users to the homepage when switching from the German version, similar to the behavior observed when switching to Estonian. 2. Alternatively, complete the translation for the missing content (e.g., trips under the Griechenland category) in English. This will likely resolve the 404 error by displaying the translated trips instead of an error page.
