Hi Jason,
I did delete the old checkout pages and did run the checkout wizard again. I had it working on my local machine (did not test whether the transaction goes through with paypal) but the site connected and the option to pay with paypal came up.
Now, after embedding the code in my site template I have 2 problems:
1 = If I test it locally and choose papal as a payment option I am immediately referred to the checkout_failure.php page. Is it possible that there might be a conflict with another css code or so in the template? Because I believe it did work before I embedded it into the template code.
2 = I can not test it on the remote server because once I try to choose paypal as a payment option, enter shipping information and clicking continue = the page goes gray but no loader appears and page does not change or connect. I was looking all morning to see whether I am missing a file on the remote server but it looks like everything is uploaded correctly.
Checkout with AuthorizeNet works perfect.
Any help is appreciated.
Thanks a lot and best regards,
Joerg
