Problem: If you're using WPML with Greek as the default language and English as the secondary language, and you encounter 404 errors across all pages in both languages after deleting a post or page in English, it might be related to caching issues. Solution: We recommend checking your LiteSpeed Cache settings. Specifically, ensure that the auto-purging of the cache is enabled. This setting is crucial for automatically clearing the cache when posts or pages are updated or deleted, which could prevent the 404 errors you're experiencing. You can find more details on configuring LiteSpeed Cache with WPML here: LiteSpeed Cache and WPML configuration.
If this solution does not resolve your issue, or if it seems outdated or irrelevant to your specific case, please open a new support ticket. We also highly recommend 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. For further assistance, you can contact us directly at WPML support forum.
