Gregorian date not showing up

Have the settings on: heb-greg on the settings page – tried adding this shortcode to the page with no luck [today_hebdate] – have added the widget to the page also no luck. Is there another shortcode I can add to show both Gregorian date and the Hebrew date – am not good at going into the code to add PHP – do not want to mess with my templates.

Thank you! Plugin looks great
