Mailchimp Server Error when a user is already subscribed

    Hello,

    I use this plugin on my website. The newsletter subscription is done in a custom registration function that use the WordPress API. So I had only add this checkbox : <input type=”checkbox” name=”mc4wp-subscribe” value=”1″ />
    to the form like said here : https://mc4wp.com/kb/add-sign-checkbox-custom-form/

    The plugin do his job and subscribe the user, but when a user is already subscribed to the list, it stops my registration script to display a Big Error page (tried to translate well) :

    MailChimp for WordPress – Error

    The Mailchimp server sent the following error message after your subscription request :

    [email protected] is already subscribed to the list.
    Here you can see data sent to Mailchimp :

    Email Address :
    [email protected]
    Merge vars :
    Array
    (
    [NAME] => Jane Doe
    [FNAME] => Jane
    [LNAME] => Doe
    [OPTIN_IP] => 11.111.111.111
    )

    This message is only visible to administrators in order to allow debugging.

    I got this message with WP_DEBUG constant to true or false.

    I tried to hack the plugin to avoid this by override to true the update_existing_user arg but it didn’t work.

    Is there a way to get around this bug please ? It’s really annoying to block user registrations for a little issue like that.

    Kind regards.

    Hi Mista-Flo,

    This message should only be shown to administrators. It does so through a check to the currently logged in user to see if they’re allowed to manage_options, like this:

    current_user_can( 'manage_options' )

    Are users registering on your site as administrators?

    Let me know, would love to get this fixed for you and improve on the debugging process.

    I guess it’s linked to a bug that allow all users to have administrator rights in the website, I don’t know why, when I check in the DB or programatically user’s capabilities, I don’t see any admin cap’. Is it due to your plugin or is there no chance ?

    By the way, is there a workaround to remove this mailchimp error ? Even if I have to hack a little bit the plugin.

    Thanks for your help.

    Hello Mista-Flo,

    Do you see the error even if you test the form when you are not logged into the website?

    Hi,

    I fix the issue about all users had admin capabilities. But now, my script is not executed and Mailchimp plugin redirect me in the home_url after trigger the submit button.

    When I deasctivate Mailchimp plugin, it works. Does the plugin redirect to home_url whithout warring the user when he is already subscribed to a newsletter ?
