Every thing was working fine on my site.
Just few days ago I found a problem searching and installing a plugin. I got following error:
An unexpected error occurred. Something may be wrong with WordPress.org or this server’s configuration. If you continue to have problems, please try the support forums.
I googled hours, i found many of same problem thread already active under http://wordpress.org/support/forum/how-to-and-troubleshooting.
One of the thread suggested me to add these ips into etc/hosts/ file of the root hosting account
But in my root directory there is no *hosts* file. Any one please help.
