You should be able to go to you style.ss folder, and at the top, you'll need to swap out Godaddy and the relevant URL's in order to make sure the "Action Functions" that call on "Author/URL" call out your new information and pull that new info into your footer. Another easier way is using a plugin, "Remove Footer". Cpanel is the easiest. Start with style.css and then also style.rtl.css.
Going into site-footer/site-info etc., might not work if you haven't gone to the root of the issue which can only be found in your style.css/style-rtl see here for a short video: https://goo.gl/RuZNMK
