 * Hi There!
 * I’m trying to add my Mailchimp API key, but when I copy it (from the Mailchimp
   website) and paste it into my website and click on “Save Changes,” the page reloads,
   but nothing changes. It still shows “Not connected.” 🙁
 * I’ve tried it on another browser / Deactivate plugins… Same issue.
 * Thanks for your help.

 * When you save the API key and the page reloads, do you maybe see some kind of
   error message at the top of the screen?

 * Ok. Problem solved: It was the WP database: I had exceeded disk space.
 * I cleaned up the database (using another plugin), so the API key works perfectly
   now.
 * Thanks for your help!!!
