Problem: You are experiencing a critical error in the backend when using the WPML String Translation plugin, which prevents you from logging in unless the plugin is deactivated via FTP. Solution: We recommend taking a full backup of your site before attempting to reactivate the WPML String Translation plugin. It's crucial to ensure that the WordPress REST API is enabled, as WPML relies on it for some functionalities, including communication with translation services and the Advanced Translation Editor. Keeping the REST API enabled is also essential for many core WordPress features. For more details on REST API dependencies, please visit https://wpml.org/documentation/support/rest-api-dependencies/.
If this solution does not resolve your issue or seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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 problem persists, please open a new support ticket for further assistance.
