Problem:
The client is experiencing Internal Server Errors when using WPML for string translations, which seem to be caused by redirects related to the .htaccess file being incorrectly overwritten. This issue is typically due to another plugin causing frequent rebuilds of WordPress rewrite rules.
Solution:
1. Identify the plugin that is frequently calling

flush_rewrite_rules(true)

and request the developer to modify this behavior.
2. Implement a temporary workaround by adding a code snippet to ensure rewrite rules point to the actual site root rather than a language folder.
