Lost footer with editing
Try to clear your site cache through system and settings, and try changing your theme back.
In the elements folder you will find a file called footer. Edit it with a text editor, and there you have it. If your not familiar with html you will have to google some stuff like href, but thats how its done.
But more to the point, there has to be an easy way to edit in a theme that doesn't have "edit" in the footer
Type this into your browserwww.www.yoursitename.com/index.php/dashboard... this will get you into the dashboard, and from there you can edit.
