So the issue is settings->Site Languages does not support Hungarian, but I need Hungarian most of my clients does not speak anything else. Also we are not part of the EUR zone so it would be nice to have HUF as the currency... but one problem at a time...

I can change some of the text by indejcting js to my site, but there is just to much to change at this point. Login and the pop up login windows? The whole part of the Checkout? The cart?

So is there a way to get access to the base code of my site and just change it? I imagine these texts originate from somewhere in the code, so I should be able to hardcode them?

What should I do? How to change these to hungarian if squarespace does not support them?

Check this article by a Circle Member https://bycrawford.com/blog/how-to-change-the-default-site-language-on-squarespace

But Hungarian is not in the list as I mentioned it above. "So the issue is settings->Site Languages does not support Hungarian"

Also Weglot (https://www.weglot.com/guides/squarespace-multilingual-site, which is the supported extension for mulit language sites) does not translate the checkout process..

"And, if you have an ecommerce Squarespace site, your checkout cannot be translated which takes away any user-friendly aspects you were hoping to build with a multilingual website – especially from an ecommerce point of view. As well as your checkout, any automatic emails sent from your website will remain in your original site language."

Can you pls share site url ?
