Paypal module v1.0 for 2.2MS2 australia

[pjahealth]

Hi All,

I am trying to add paypal IPN to my shop in Australia. I have uploaded the files to my shop but in the payment module section I get this error message:

 

Fatal error: Cannot redeclare class paypal_ipn in /var/www/shop/includes/modules/payment/paypal_ipn.php on line 13

 

Is there something simple I have forgotten or did I not add it correctly? Can anyone help?

 

Thanks

PJA
