No scripts at all are loading in your footer.
Some things that can cause this:
1. The wp_footer() function has been removed from the footer.php template.
2. A plugin is causing a PHP error causing the rest of the code not to print.
I’m assuming you have no plugins installed?
You can try re-installing the theme in case something is corrupt in the files you downloaded.
Another option is to check the error_log file for any errors.
