Google BOT error with WordPress

Hiya,

I keep getting notices that Google can’t access my robots.txt.

My robots.txt is as follows:

User-agent: *
Disallow: /wp-admin/
Disallow: /wp-includes/

Sitemap: http://url.com/sitemap.xml.gz

I’m using WP and the settings about allowing it to be index are set correctly. I can access my robots.txt but when I fetch it on WMT it shows this:

Unreachable etc

Anyone else had this issue and had a fix? My WP allow settings are also corrrect.
