Fatal Error on activation

    Hello,

    I received the following “fatal error” message when I tried to activate your plug-in:
    Fatal error: Cannot redeclare class Mailchimp_Folders in /public_html/wp-content/plugins/yikes-inc-easy-mailchimp-extender/Mailchimp/Folders.php on line 3

    I tried de-activating one other Mailchimp plug-in that I had installed, but I still get the error. Do I have to delete the other Mailchimp plug-in altogether in order to avoid getting this message?

    Thanks in advance for your time and help!

    Best,
    Robert

    Hi Robert,

    The error is occurring because you have another MailChimp plugin installed. You shouldn’t need to uninstall the other before installing ours, but if the error is persisting you may want to try deleting the other first.

    The other plugin is using the same class files provided by MailChimp to communicate with the MailChimp API.

    Try uninstalling the other plugin and give ours a shot. You shouldn’t have issues activating ours if no other MailChimp plugins are installed.

    Thanks,
    Evan

    You’re right — I actually had a second one. Once I deactivated it, I was able to successfully activate your plugin.

    Thanks again!!

    I have the same conflict with another plugin using MailChimp. The develop comments: It appears they aren’t checking for the presence of the Mailchimp class before including their copy of the API files.

    Our add-on uses the official MailChimp provided API wrapper and we use the following to determine if the MailChimp API has already been loaded by another plugin before including our copy:

    if ( ! class_exists( ‘Mailchimp’ ) ) {
    require_once( ‘api/Mailchimp.php’ );
    }

    It seems they have renamed the MailChimp class to wpyksMCAPI.

    Can you provide a fix for how you load the API files to prevent conflicts?
