Problem: The client is experiencing issues with the 'sitepress-multilingual-cms' plugin when deploying to AWS due to its case-sensitive file system. This results in PHP Fatal errors and warnings, causing the website to break and throw 500 responses. Solution: We recommend updating all WPML plugins to their latest versions, as this issue has been addressed in the recent WPML release (version 4.7.6).
If this solution does not resolve your issue or if it becomes outdated, please check related known issues, verify the version of the permanent fix, and confirm that you have installed the latest versions of themes and plugins. If problems persist, we highly recommend opening a new support ticket at WPML support forum.
