Support » Plugin: Add-on Gravity Forms - MailPoet 3 » Fatal Error – Plugin Conflict

  • Hi there,

    We have noticed, that with a recent update of Gravity Forms, several of our customer’s websites are now returning a fatal error (example below) when one of their Gravity Forms (that had a MailPoet feed enabled) is filled in.

    Fatal error: Call to undefined function array_column() in /home/canetoadtough/public_html/wp-content/plugins/add-on-gravity-forms-mailpoet/add-on-gravity-forms-mailpoet.php on line 186

    Deactivating the plugin clears the issue (however we require it) and we have also attempted to deactivate, delete and reinstall again and the issue has remained.

    When this plugin is active, the Gravity Form still captures the entry and the subscription request still goes to the correct database.

    It’s a bit of a strange one and is effecting a number of our sites.

    If you require any further information to help troubleshoot, that would be fantastic.

    Kind regards

    The page I need help with: [log in to see the link]

  • Hi @karenahl,

    Looks like you are using a older version of PHP, probably your server PHP version is less than PHP 5.5 where array_column is not supported.

    However, we are going to release a patch to solve this problem.


    Hi @karenahl,

    We just updated the plugin to latest. This version will surely solve this array_column problem.

    Please update or reinstall the plugin.


    Hi Tamim71

    Thank you for your responsiveness and thanks for the PHP tip.

    Also, we can confirm that the update has worked perfectly.

    Thanks once again!
