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:
127.0.0.1 localhost.localdomain localhost
188.116.55.217 zako.vladoiu.net zako
72.233.56.139 api.wordpress.org
72.233.69.6 jetpack.wordpress.com
72.233.56.138 downloads.wordpress.org
72.233.56.138 jetpack.wordpress.org
72.233.69.89 rest.akismet.com
72.233.69.88 rest.akismet.com
66.135.58.62 rest.akismet.com
66.135.58.61 rest.akismet.com
173.194.70.109 smtp.gmail.com
76.74.254.123 dashboard.wordpress.com
173.194.65.106 blogsearch.google.com
173.194.*.* google.com
While this fixes the error say :
WP HTTP Error: Couldn't resolve host 'rest.akismet.com'
