Hey Sculley,
the submit button is present, it is not seen because it has the same background color as the page, set by one of the Theme Options fields; to correct this, please download this archive I’ve prepared, unzip it, and upload the contained file into the theme folder (/wp-content/themes/Fuji/) via FTP. Please let me know if it fixes the issue!
Sincerely,
Andrii / Satori Studio
