I voted broken

I didn’t know how to configure it when the prompt came up after I renamed my website so I deleted the old one and added a new contact 7. Upon adding the new one it took out all the pictures on the entire site by leaving them with a question mark and whatever I’d named the picture.

I did go back and redo all the pics.
The only thing I don’t know how to fix is to add the logo back in. I tried and tried again and again and don’t know how to remove it’s question mark and have it take the product.

Can you add an easy fix for someone that doesn’t speak algorithms?
