get error message in cart when checkout button clicked
Hello,
I am getting the following error message when I click checkout in ecart.
Warning: Cannot modify header information - headers already sent by (output started at /home1/isaacsgr/public_html/meganisaacs/cart.php:200) in /home1/isaacsgr/public_html/meganisaacs/cart.php on line 253
I do not get it on my local server, only when this file is live.
I checked the script for white spaces, I did not see any, although could be wrong.
Thank you,
K
