[Resuelto] No aparece nada en "Traducción de cadenas"

Problem:
I am experiencing an issue when trying to add a new translation string for a button text. The "Translation of Strings" panel is empty, and clicking on "Language of Domains" does not respond.

Solution:

Consider updating the PHP version to at least 7.0. Refer to the minimum requirements here: https://wpml.org/home/minimum-requirements/
After updating PHP, check if the issue persists or is resolved.
