Hi, I try to import from Mailchimp Importer for Mailster, I clicked on next button and then enter the API and then when I clicked on next the page and it is just loading and loading, is a problem with in the plugin

Is there a way to set it to import subscribers with their groups and/or tags?

When I go to import my Mailchimp subscribers I instantly get a white screen with this error:

Error thrown

Call to a member function get_tgmpa_url() on null

I am on WP Engine, and there are no errors in the error log. Is there something, in particular, I should look at to help troubleshoot this?

Side note – I do have another plugin that integrates with Mailchimp. The Gravity Forms MC extension.
