Need help ASAP with PayPal strings revealing private data from cart. Help

When customers use the PayPal option they are getting sent back to an empty cart without the checkout process taking place. The site does take them to PP and they begin the process. When submitting payment, this happens. This problem is intermittent and PayPal gave me error codes on the phone pertaining to either an extra comma or $ sign being inserted or an improper format coming from the cart.

I noticed that one of my pages was reverting to www from non-www. This caused the sting to vanish and sent nothing to PP. I fixed it with a forced redirect in htaccess. Works like a champ again!

Make sure to delete the var_dump() line from the failure page. That should have only been there for debugging.

Many thanks for getting back to me Ray! I'm proud to have figured this one out. It was, as you said, the dump script added to the failure page during de-bugging. No one caught it until an invalid credit card was used. BTW: People who have credit cards declining are just the ones I don't want the full string being visible for, so I'm glad it came out the way it did and not after someone cleaned me out.

I appreciate your being there to help so quickly. Your tireless service is huge and what I mention most to those I recommend WebAssist to.
