Problem: The client migrated their website and encountered issues with missing translations and incorrect URL settings. They also faced problems with bulk marking pages as translated and accessing translation credits. Solution: 1. We merged the old site settings with the new one, enabling the client to see available translation credits and ensuring the translation memory functions correctly. 2. To address the issue with the Advanced Translation Editor not displaying old translations, we recommended cancelling current ongoing jobs at WPML > Translation Dashboard > Jobs, then re-sending the content for translation from WPML > Translation Dashboard, assigning the job to themselves, and accessing the translation at WPML > Translations. 3. For bulk marking translations as complete, we clarified that this option is only available under the "Translate Everything Automatically" mode and suggested sending those jobs for translation from the Translation Dashboard, using automatic translation if credits are available, or translating them manually.
