    Hello, i have this error E_WARNING: Cannot modify header information – headers already sent in /var/www/vhosts/**/httpdocs/wp-content/plugins/mailchimp-for-woocommerce/bootstrap.php on line 1441 in debug.log.

    This error appears when i complete a purchase as a guest im my eshop.

    I open the file but there is no whitespace in row 1441. The row 1441 is the: ‘httponly’ => $httponly as the he whoe function appears here:

    function mailchimp_set_cookie($name, $value, $expire, $path, $domain = ”, $secure = true, $httponly = false, $samesite = ‘Strict’) {
    if (PHP_VERSION_ID < 70300) { @setcookie($name, $value, $expire, $path . ‘; samesite=’ . $samesite, $domain, $secure, $httponly); return; } @setcookie($name, $value, [ ‘expires’ => $expire,
    ‘path’ => $path,
    ‘domain’ => $domain,
    ‘samesite’ => $samesite,
    ‘secure’ => $secure,
    ‘httponly’ => $httponly,
    ]);

    Can you help?

    (PHP version 8.0.28)

    Regards,

    Nikol

    Hi @nikolsou, thanks for reaching out. As a first step for troubleshooting. Let’s try to work through the following:

    • Verify the latest plugin version is being used (v2.8.3 at the time of this post)
    • Switch themes to the default WooCommerce one, deactivate all plugins except WooCommerce and Mailchimp for WooCommerce, and test the scenario again – ideally in a staging enviornment.
    • Test for conflicts by following this guide, WooCommerce: Fixing Theme and Plugin Conflicts:?https://docs.woocommerce.com/document/how-to-test-for-conflicts/
    • Check for possible caching issues caused by the hosting provider.
    • Try uninstalling and reinstalling the plugin from scratch.

    Let us know if any of those help you resolving this issue.

    Thanks!
