Footer Copyright

Hi there,

I am making a site for a friend and when I have tried customising the footer copyright with their details and my details it hasnt changed in the editor. When i hover over “themes & Co” it actually links to my portfolio but shows your text. Can you please help me change this? I have been through the editor numerous times and cannot find what is happening.

Here is a screen shot – https://i.imgur.com/r4eYtSU.png

Thank you in advance.
