Error on Payment
I have built an ecart a while ago and make been selling .mp3 files etc using it fine.
However, occasionally customers come back and tell me they get this error.
Notice: Undefined variable: ParamProductID2_WADAsiteezyecproducts in /home/siteezy/public_html/pp_confirm.php on line 56
Warning: Cannot modify header information - headers already sent by (output started at /home/siteezy/public_html/pp_confirm.php:56) in /home/siteezy/public_html/WA_SecurityAssist/Helper_PHP.php on line 67
Could you tell me what this is, as I have a lot of successful purchases made via this system, but it still appears from time to time?
