I downloaded a new theme today, my first theme download, and I did not "preview" it before I installed it. Now I am getting the following error when I attempt to view or log-in to my site:
Fatal error: Call to undefined function register_nav_menu() in D:\Hosting\6108890\html\index\wp-content\themes\voidy\functions.php on line 267
It is entirely probable I did something wrong here, but I need to regain access to my site. If I delete the downloaded theme from my web hosting content file manager, will wordpress go to the default theme? Is there a way to "backdoor" into the admin panel so I can change my theme back to the default?
