The translations no longer work since WordPress 6.7.

Here is the error message :

The _load_textdomain_just_in_time function was called incorrectly. Translation loading for the packlink-pro-shipping domain was triggered too early. This usually indicates that some code in the plugin or theme is running prematurely. Translations should be loaded at the init action or later. (This message was added in version 6.7.0.)
