Hi, I need help to remove the Copyright at footer.

Hi there,

1. Copyright. Customiser > Layout > Footer and in the Copyright field just enter:

<span></span>

2. That Logo is in the Customiser > Layout > Primary Navigation > Logo.

Thanks David, that works.
I do have another problem, please check the top left. There seems to be missing a logo or something.
What do you suggest I do with it? How do I work around that?

I am not seeing that on my browser, that would be the Customiser > Site Identity Logo which looks the same as Nav logo on my browser.

Great, thanks!

You're welcome
