    I have seen multiple threads with this issue, but never saw the resolution. I didn’t change any code but all of a sudden I am receiving this error:

    exists##Product already in the wishlist.
Warning: Cannot modify header information - headers already sent by (output started at /home/neccoas/public_html/rcaputo/crowdshop/wp-content/plugins/yith-woocommerce-wishlist/yith-wcwl-ajax.php:47) in /home/neccoas/public_html/rcaputo/crowdshop/wp-includes/pluggable.php on line 1178

    Is there a fix for this issue? Any help would really be appreciated.

    Hi caputodesignz,

    do you have this issue with the latest version of YITH Woocommerce Wishlist ?

    I used to get the same with version 2.0.2:

    Warning: Cannot modify header information – headers already sent by (output started at /usr/local/pem/vhosts/291969/webspace/httpdocs/xxxxxxx/wp-includes/plugin.php:885) in /usr/local/pem/vhosts/291969/webspace/httpdocs/xxxxxxx/wp-content/plugins/yith-woocommerce-wishlist/includes/functions.yith-wcwl.php on line 149

    Now the error is gone, but I get another one (v. 2.0.3):

    Notice: yith_wcwl_products cookie cannot be set – headers already sent by /usr/local/pem/vhosts/291969/webspace/httpdocs/xxxxxxx/wp-includes/plugin.php on line 885 in /usr/local/pem/vhosts/291969/webspace/httpdocs/xxxxxxx/wp-content/plugins/woocommerce/includes/wc-core-functions.php on line 548

    Hi BusinessBloomer,

    can you please post a link where we can check the problem? Have you tried disabling other plugins you’re using on your wordpress installation?

    It seems someone prints unexpected output before wishlist plugin can set its cookie

    Let us know 🙂
