Over the last 24 hours, Googlebot encountered 2 errors while attempting to access your robots.txt. To ensure that we didn't crawl any pages listed in that file, we postponed our crawl. Your site's overall robots.txt error rate is 100.0%

There are several reason but most important is your Robots.txt file having some problem. Go to the webmaster tool and Get the information and Check the parameters of Robots.txt file.
It will properly guide you to remove your issue.

I think that if you didn't understand robots.txt is do delete this file completely in order to allow all search engines to index your site.
