    Hi! I do not think the problem has anything to do with WP Downgrade. Anyway: You should try to delete the plugin “yikes-inc-easy-mailchimp-extender” via FTP. Just delete the entire folder (but download it for backub) and then try login again.

    Thanks for the prompt response! I’ll look into that now.

    Great, that worked, thanks!
