“Warning: Cannot modify header information”

  • When I duplicate a completed order, it’s working but I always get this message right after it loads the page. What could be the issue?

    Warning: Cannot modify header information – headers already sent by (output started at /wp-content/plugins/wc-duplicate-order/classes/class-clone-order.php:37) in /wp-includes/functions.php on line 6029

    Hi Eric,

    I am unsure why this would be as the duplication has no problems this end, perhaps a conflict of another plugin?

    Can you change theme to a default wordpress one and make sure you are updated to the latest woocommerce, disable all other plugins and give this a test please?

    Many Thanks
    Jamie
