Fatal Error - jigoshop

Looking for some assistance with a plugin update = fatal error.

Not sure where to start... this is on our front page until I disabled jigoshop.

Fatal error: Call to undefined function jigoshop_get_template_part() in /home/content/98/3597198/html/ChaiFashions-NEW/wp-content/themes/maya/inc/shortcodes-jigoshop.php on line 261
