Hello fellow Zenners.

I have been using Zen Cart for some time now and have been running a online store quite successfully.

I have recently been attempting to install PayPal Express Cart. I have gone through all the steps as listed on numerous posts and have found an interesting problem.

I was having the problem where Paypal would work right up to the 'Pow Now' point (allowing you to login to your paypal account etc) all the relevant info was being sent to paypal, price, postage etc. When trying to process the payment it would come back with an error "Unable to process payment at this time. You have not been billed. please return to merchant site and select another payment option"

Looking into this further. I found it only did this if I selected a parcel option from my installed OzPost module. If I selected "pick up from store" ie no postage PayPal would process the payment with no errors.

I also found that while I had the PayPal module active I would start to get errors with OzPost and then it would completely disappear from shipping options.

When I disable PayPal, Ozpost comes back to life.

If I disable OzPost PayPal seems to play nicely.

All, very strange and got me completely stuffed.

Everything has been working very well until I enable PayPal.

Anybody got any ideas.

Cheers
