Why are the pictures not showing up?

Question

opencart

Good day to all, please advise. Scrolling through the forum , I came across a topic with a multishop, twisted it, tweaked it, it seemed to work out, but when I started the general settings of the site (via the admin), a strange side came out. I upload a
logo with a favicon to site1, everything is fine, but when I upload it to site2 , then I don’t see a logo or a favicon, even the text in the logo doesn’t want to change the first time and the template doesn’t work. How so, tell me?
