Problem: If you're experiencing an issue where WPML requests the translation of an entire page after updating a single block on your homepage, this is due to the Advanced Translation Editor (ATE) treating modified content as new because there's no translation memory match for the updated paragraph. Solution:
Since the paragraph content was modified and there is no existing translation memory match for the updated paragraph, the Advanced Translation Editor treats it as new content and requires it to be translated again as a new paragraph. However, the existing translation will still be displayed on the front-end.
If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
