 * Hi,
 * I’ve installed the plugin and am using the API key from my mailchimp account 
   however I keep getting a “Uh-oh, we were unable to verify your API Key. Please
   check them and try again! The server said:Invalid Mailchimp API Key” error.
 * The site is [http://www.cornerstoneofsheridan.org/wp](http://www.cornerstoneofsheridan.org/wp)(
   wordpress). Host = GoDaddy.
 * Thanks for your help,
 * John

 * Hey there, John!
 * Sorry to hear that you’re having trouble getting the API Key to validate. Generally,
   when that’s an issue and the full API key is getting copied (including the us#),
   it has to do with the host blocking certain ports. Your best bet would be to 
   get in touch with your host to ensure that there aren’t any outbound calls being
   killed off. We’ve seen this issue before, here:

 * If we can assist with anything else, please don’t hesitate to let us know.
 * Cheers
