For some reason, in my list of plugins, the MailChimp and PayPal addons are giving me the message, "Register your copy of Gravity Forms to receive access to automatic upgrades and support. Need a license key? Purchase one now." However, the main Gravity Forms plugin does not have the same message. When I click on the "register" link, all of the information is correct. I saw a similar issue on the forum, but it was dated a few months ago and seemed to be related to your server changes. What should I do?
