Members Can't Register with MailChimp

Experienced another error with the new Membership update.

Attempting to register Member and it fails to display the next page as the following error displays:

Fatal error: Class 'M2_Mailchimp' not found in /home/thegocoach/public_html/wp-content/plugins/membership/app/addon/mailchimp/class-ms-addon-mailchimp.php on line 293

Turned off the add-on and turned it back on but still no change.

I turned off the add-on and new members can register now. However our list will be out of sync.

    Hi Jenn,

    Hope you’re well?

    Can you try the following.

    Open up & edit the following file: /wp-content/plugins/membership/app/addon/mailchimp/class-ms-addon-mailchimp.php

    Find the following (around lines 289 – 291)

    if ( ! class_exists( 'Mailchimp' ) ) {
    require_once MS_Plugin::instance()->dir . '/lib/mailchimp-api/Mailchimp.php';

    Replace it with:

    if ( ! class_exists( 'M2_Mailchimp' ) ) {
    require_once MS_Plugin::instance()->dir . '/lib/mailchimp-api/Mailchimp.php';

    I’ll report this to the developer, hopefully this should fix your issue though.

    Hope this helps
