Problem: The client is experiencing issues with translation connections not saving and resetting on subsites other than the main blog ID in a multisite environment. The issue arises when using a specific function in their theme that switches to the main site blog, queries for posts, and then restores the current blog. Solution: We explained that it is not possible to connect original content and translations between different subsites on a multisite network, as each subsite has its own tables and WPML language settings. This limitation is likely causing the observed issues with translation connections not being saved. If you're experiencing similar issues, we recommend reviewing the purpose and implementation of any custom functions that interact with WPML and multisite setups.
