I keep getting this kind of error in my WP dashboard:

WP HTTP Error: Couldn't resolve host

I tend to believe it's a DNS issue although all was working OK before. What I have done is altering the /etc/hosts file and adding stuff like:               localhost.localdomain localhost zako

While this fixes the error say :

WP HTTP Error: Couldn't resolve host ''

Put valid DNS server entries into /etc/resolv.conf.

It should look something like this:

nameserver 2001:db8:24fe:381::37

The actual values will be supplied by your ISP, hosting provider or datacenter. Or you can use public DNS providers such as Google Public DNS.

Those don't look like normal recursive DNS servers. They probably aren't. – Michael Hampton Nov 13 '12 at 23:12
