Default System Language is always English how to fix?

Hi Everyone For this amazing community.

I try to choose default active languages (arabic,etc) but nothing happen and
is shown me that the default lang is Arabic,etc but the interface is still in English with no change.

How I can fix this issue ( I tried v12 and v13, and I use XAMPP)

Thank you a lot

I will try MAMP server, and giveback my result.

Luai, this problem usually occurs because the relevant language/locale is not installed in the machine. Installing it depends on your platform, so search Google for something like “MAMP install locale”. Let us know how you get on, and give a link to anything useful you use : ) Ross

Thank you for your suggestion, I will try to fix locale issue and giveback my result :slight_smile:
