Problem:
You are experiencing an E_ERROR after updating plugins, specifically a ReflectionException indicating that the class "WPMLStringTranslationInfrastructureTranslateEverythingUntranslatedStringsFactory" does not exist.
Solution:
If you're encountering this issue, we recommend you follow these steps:
1. Download the latest version of the WPML plugins from https://wpml.org/account/downloads/.
2. Disable all WPML plugins.
3. Delete the plugins (your settings and translations will be saved in the database, so they won’t be lost).
4. Upload the newly downloaded WPML plugin by going to Plugins → Add New → Upload Plugin.
5. Activate the plugins.
Ensure you back up your database before making any changes.
