 * Thanks again! I’m back on the previous version, and the dashboard works OK for
   me now.
 * Problem solved.
 * Except for one thing…. WordPress is still telling me I need to upgrade MailChimp
   to 4.0. Is there anything you can do on your end to fix that?

 * Thanks, Danny, I can do that. Will I lose any plugin customizations I have made?
   Or are they in the database or some other folder?

 * The WP site is up, and I can even log in as administrator, but any attempt to
   open the WP dashboard leads to a page including the above warning and error message.
 * I have downloaded the previous plugin version zip file. But now I don’t know 
   how to install it if I can’t get to the WP dashboard. How can I do this?
 * (To attempt to protect my privacy, I replaced identifying information in the 
   above messages with four dots – ….)
 * My guess was that there is a bug in the latest upgrade of the MailChimp for WP
   plugin, but I don’t know enough PHP to be able to find it or fix it.
 * Can anyone help?
