This thread is resolved. Here is a description of the problem and solution.
Problem:
If you're experiencing issues where all translations are missing after reverting your website to a previous date, and you're concerned about losing translations for which you've already paid.
Solution:
First, we recommend checking the translation memory where all translations are stored. You can retrieve your previous translations from there without incurring additional costs. Follow the steps in this screen recording: https://go.screenpal.com/watch/cZXFfInVquM to add the translations back to your pages. Additionally, you can initiate an automatic translation process for all pages; rest assured, you will not be charged again for translations that have already been paid for and are stored in the translation memory.
Please note that this solution might be irrelevant if it's outdated or not applicable to your case. We 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. If the issue persists, please open a new support ticket at WPML support forum for further assistance.
