Problem: You are trying to update WPML plugins on your WordPress site and encountered a 'Security Check Control Failed' error during the upload process on the live site. Additionally, updating via FTP caused a fatal error that broke the entire site, including the WordPress admin panel. Solution: If you're experiencing this issue, we recommend you try the following steps to safely update your WPML plugins without breaking your site: 1. Ensure you have a complete backup of your site. 2. Deactivate all plugins on your site. 3. Update all WPML plugins. 4. Reactivate the plugins that were previously deactivated.
This method helps to prevent conflicts that might arise from other plugins during the update process.
If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, please check the related known issues and confirm that you have installed the latest versions of themes and plugins. We highly recommend opening a new support ticket at WPML support forum for further assistance.
