Hello,
1) Sorry but there is no option in Theme Settings to change the currency Arabic to English. Because the currency is Woocommerce functionality and our theme doesn’t influence.
2) Please check how it works with the default WordPress theme just to check whether the issue is with our theme or not. Because the shipping options are Woocommerce functionality and our theme doesn’t influence.
3) You can use logo images as SVG, png, or jpg.
4) Please provide a relevant screenshot of the specific area which you are asking about to check it myself and help you out accordingly.
Because currently, I am unable to see the gallery.png file that you attached as a reference.
Regards.
