Just activated this plugin on my wp 3.4.2 site and when I enter my apikey I get the following error:
Uh-oh, we were unable to verify your API Key. Please check them and try again!
The server said:Could not connect (ERR 0: php_network_getaddresses: getaddrinfo failed: Name or service not known)
I tried creating a new apikey and received the same error from your plugin.
