[Resolved] Page not translating with ATE and stays to "in progress"

Problem:
The client was experiencing issues with pages appearing translated in the Advanced Translation Editor (ATE) but remaining 'in progress' without completing the translation. Additionally, updates in String Translation for 'elementor-17976' failed, showing 'Translation update failed.'
Solution:
We recommended the following steps:
1. Create a full backup of the site.
2. Delete the translated page and remove it from the trash.
3. Apply the workaround described on the errata page: https://wpml.org/errata/line-breaks-are-ignored-when-using-the-advanced-translation-edior/
4. Check and apply another workaround for the WPML plugin from: https://wpml.org/errata/wordpress-6-7-mo-files-not-loaded-and-leading-to-missing-translations-on-front-end/
After these steps, if the issue persists, our 2nd tier specialists found an error in Elementor Pro and applied a workaround described here: https://wpml.org/errata/elementor-php-fatal-error-call-to-a-member-function-get_main_id-on-null/
