Robots Txt Blocking Google From Indexing Site!

Hello, I’m facing a very frustrating problem with my robots. I tested it using google webmaster tools and it returns ok – meaning it shows that my main site is not blocked (themaverickpaper.com) but when I submit my sitemap, it returns 50 issues saying my robots blocks many urls including the main home page.

A search on google for the said site returns this: “A description for this result is not available because of this site’s robots.txt – learn more”

Help pelase!
