Is Italian listed before English in your browser settings?

No. You need to order your browser languages in the order you actually prefer them. You communicated a preference (Italian over English) when it's not what you actually want. Rearrange the language order to reflect your actual preference and the software will honor your preference. That's the entire point of the browser communicating that preference to begin with.

It would actually help to tell me what is the content of the Accept-Language HTTP header your browser sends. You can find that by opening dev tools on your browser, reloading the page, clicking on the Network tab, then click on the entry for the page that loaded (should be at the top), and look at the Request information. It should have the Accept-Language header stated there.

I have a suspicion, but I cannot be entirely sure until I see the actual header content.

Thank you! That helps a lot. My hunch was right. There was an inversion in the logic of the restoration script's Accept-Language parser. It ended up sorting languages in the reverse order than what was received from the browser, thus putting Italian before English in your use case. The unit tests were also wrong. They were passing, but testing the wrong premise. While I was at it I also saw another small deviation from RFC 9110 §12.5.4 which I fixed. These fixes will make into the next release of Akeeba Backup.

Since the restoration script is embedded into the backup archive – what you are using IS NOT Kickstart; Kickstart is just the standalone application extracting the backup archive – I recommend using a temporary browser (e.g. Chromium) with only one language set up for now.
