Hi Ambrosa,
Thank you for your interest in translating the WP Statistics plugin into Italian! It’s great to have contributors like yourself.
Regarding your question, it’s typically recommended to translate the ‘STABLE‘ version as it affects the current live version of the plugin that most users interact with. Once your translation is submitted, it will be reviewed and approved by one of the Translation Editors.
As for the ‘Translate Live’ option you mentioned, it is indeed designed for the development version, which is why it works only in that context. It allows contributors to see how their translations fit within the actual working environment of the plugin.
If you have any more questions or need further assistance, feel free to post your question in the appropriate category on the WordPress.org support forum. They’re a helpful community!
Best regards.
