Custom logo in header

I have the Go theme and in the customization of the theme, I can see the logo and the tagline. When I view my site on Chrome, everything is fine and where it should be. But everybody else can’t see my logo, they just see the tagline. When I use Safari, can’t see the logo, just the tagline. 

I have changed themes to see if it would make a difference, and it doesn’t. I have also remove the site title to see, and no different. I really don’t know what to do. 

Thanks in advance !
