Problem: The client changed the main language of their website from Turkish (TR) to English (EN) after moving to a new domain and encountered an error when logging into the original domain with the Turkish language set as the main language. Solution: We recommend updating to the latest version of WPML, which at the time of the support was 4.6.8. This update can be downloaded from the WPML changelog page. After updating, the client should use the "mark it as copy" option designed for such cases where the domain and main language have changed.
