I disabled WA_Globals shipping and I was able get through the PayPa checkout successfully. When I was sent back to my site after PayPal check out, I was on the pp_confirm.php?token=EC-86N79974B5394774B&PayerID=WJG434MBL78ES page. At the bottom, I clicked "CheckOut" and was sent to pp_confirm.php with the following warning:
Warning: Cannot modify header information - headers already sent by (output started at /home/content/f/u/n/funphotobooks/html/pp_confirm.php:409) in /home/content/f/u/n/funphotobooks/html/pp_confirm.php on line 739
How do I fix this?
