Where should this code be added? Thank you! 

I have a share button on the blog post page, but it is only available to share to the app that I downloaded on PC or mobile, how can I share it on the social media webpage? Thanks!

Hey guys, I've just solved this problem, all I need to do is set the type to another, save it, then reset the type to the right one, save it again, refresh the home page, and all done. 

I set up the type of product organization in English,  not the custom one, actually the whole site is in English, but it still shows the other language on the storefront, what should I do?

I use Supply theme, please check the pic below, what should I do about this? And I add sitemap succeeded but 0 of URLs were found, what is the problem?
