My web site is Foothillsevents.com

I have spent many hours adjusting the SEO in WordPress, however when I search for the “Foothills Events Grass Valley” this is what I see in Google:
Foothills Events Center
foothillsevents.com/
A description for this result is not available because of this site’s robots.txt – learn more.

I unchecked the search engines permission under Settings>Readings. How can I find the file or code that’s blocking the site?
Thank you in advance for your help!
