I have a fresh install of 1.3.7 in my test directory (I copied the files over from my live shop to make it identical). I uninstalled all the payment modules and reinstalled them. I only have Paypal IPN and Money Order enabled.
When I test the checkout process w/ IPN, I get a warning message when it redirects me to Paypal saying "Some required information is missing or incomplete. Please correct your entries and try again." I can continue checking out, but I don't know where this is coming from. I have the latest Paypal patch applied. I don't want to use PPEC because of a few issues.
Could it be the live shop's information in Paypal interfering with IPN? I have automatic return URL and IPN URL pointing to the live shop directory. If so, is it safe to point them to my test directory?
