I am new at WordPress. My site is working fine from last few days and Google crawls all my posts but now i got red mark on robots.txt in webmaster and my last few posts doesn't crawl. I also check privacy and select "Allow search engines to index this site." I have also installed Sitemap.xml plugin and select make virtual robots.txt. Now i have installed another Special plugin for Robots.txt named as "WP Robots Txt". When i open mysite.com/robots.txt it says
# Added by SEO Ultimate's Link Mask Generator module
# End Link Mask Generator output
I want Google to crawl my site what should i do now.
