Paypal IPN help

[princeofpersia]

Hi guys, my code below works with sanbox for paypal IPN but since it has gone live it doesnt do anything, so i made emails to send me where the issue is and it keep sending me $req = 'cmd=_notify-validate';

 

could you please tell me what im doing wrong here? my db connection should be fine as it does update the users on sanbox.

 

the account im paying with in paypal keep saying payment status unclaimed. it means the reciever has not recieved the money. I checked the paypal account where i recieve the moeny and looked into my ipn history, nothing there.

 

the same ipn address is used for my account when i tested it on sanbox,

 

thanks
