Hi, I'm getting the same problem with MailPoet getting stuck on the spinning "Loading Results..." as well.
Whatever I try to load into the newsletter template (new posts, new theme etc) can't be placed into the template because of this problem.
I've tried using a different browser, uninstalling all other plugins, changing my wordpress theme and pretty much everything else that the developers suggested on the forms.
My Mailpoet version is recently up-to-date with version 2.7.
Is there any other way to fix it without changing the PHP version?
