After uploading the XLiff file, it indicated completion, and the page displayed the correct translation. However, when I clicked "Edit" and entered the editor at hidden link, the translation was blank.
Thank you for reaching out to WPML support. Before your ticket is assigned to a supporter, I’d like to provide some guidance on your query.
Please note that translations created using Translation Services and XLIFF files do not appear in the Advanced Translation Editor. To access the translation data properly, go to WPML → Settings → Translation Editor and switch to the Classic Translation Editor. Once enabled, you should be able to view and manage the translations correctly.
Let us know if these steps resolve the issue or if you need further assistance.
