Redirection to Paypal sometimes fails

[boulio971]

Hello,

 

I am using version PS 1.4.1.0

Sometimes when a user pass an order and should be redirected to Paypal payment page, he get the message "Firefox has dectected an infinite loop"

This occurs randomly

I recently activated simplified URL feature, and I have never used SSL (I saw that SSL activation can be an explication of this kind of behaviour)

 

Do you have any idea of how I can fix this ?

 

Thanks
