Hi - After uploading Constructor into wordpress, I have Constructor appearing as one of the themes available. However when clicking on the image to select it the following error occurs. Is this a user error or something wrong with the actual file. I'm not very technical so be great to get a simple response!
Fatal error: Call to undefined function body_class() in /home/lisah74/public_html/wp-content/themes/constructor/header.php on line 21
