Problem: The client is experiencing an issue where all translations, including pages, posts, and string translations, have disappeared from their website. The translations are also missing from the wp_icl_translations table in the database, and attempts to clear the WPML cache, check translation settings, disable other plugins, verify the wp_icl_translations table, and rescan the theme and plugins have not resolved the issue.
Solution: We suggested that the client first consider any recent events that might have affected their site, such as site migration, running cleanup scripts, or direct interactions with the database, as these could have reset the data. Additionally, we recommended trying to manually add a translation for a page that previously had a translation by clicking the '+' icon in the WPML translation management. This step is to check if the existing translation reappears in the translation editor.
If these steps do not resolve the issue, or if the solution seems outdated or not applicable, we highly recommend checking the related known issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the problem persists, please open a new support ticket.
