Hey! Just stumbled across this thread. If you want to change the footer credit, it’s actually pretty easy to do in the .php file.

In your site’s dashboard, just go to Appearance > Editor and then select Footer Credit.php from the menu on the right.

It’s a short .php file, and towards the bottom you should see the “Make – A WordPress Template” language or whatever it says inside some quotes. Simply edit the text to say what you want, hit update, and the text will change.
