hey. I saw a topic related to this issue, but its now closed without any solution if i m opening a new one.
I m facing this problem after submitting sitemap_index.xml to Google Webmaster Tools.
Url blocked by robots.txt.
Sitemap contains urls which are blocked by robots.txt
*Wordpress SEO by Yoast.
*Default robots.txt of WP, which means there is no robots.txt on my root, it is generator automatically by WP
waiting for a solution....
