MailChimp plugin settings page Frozen (only on sites connected to MailChimp)

  • Anyone else seeing this? It started happening after the latest WordPress update.

    On a WordPress multisite with the plugin network activated.

    Sites that do NOT have MailChimp connected yet, you can access the MailChimp plugin settings page fine.

    However on sites that had previously connected to MailChimp with the plugin, the MailChimp plugin settings page comes up but is completely frozen, can’t make any changes or even click any elements.

    Thoughts?

    I notice the plugin hasn’t been updated in a year, is this possibly a compatibility issue with the latest WordPress?

    Using Google Chrome. but it’s always worked fine before…

    Thanks!

    Anyone?

    Alos, is there a plugin update planned anytime son?

    Thanks!

    Hey there, i’ve found a solution for this problem.

    This happens because probably your API Key is not valid anymore, and the MailChimp API can’t connect to MailChimp services. So you need to configure a new API Key.

    The settings page frozen occurs because MailChimp plugin triggers an WP Error on line 583 of file mailchimp/mailchimp.php, trying to get the mail lists of MailChimp service.

    What you need to do is verify if $lists is an WP Error, then return null:

    $lists = $api->get('lists',100, array('fields' => 'lists.id,lists.name,lists.email_type_option'));
    if (is_wp_error( $lists ) ) {
        return;
    }

    Done that, you can see the Settings page and set up a new API Key.
