Problem: The client is experiencing an issue where they are prompted to log in again when switching to another domain from the language switcher. Solution: We recommend the following steps to resolve the issue: 1. Deactivate Litespeed caching. 2. Navigate to WPML->Languages and switch the URL format to POST instead of URL. 3. Resave permalinks. 4. Test the functionality again.
Note: We have reactivated Litespeed caching after testing.
