We have a Magneto CE 18.104.22.168 store. Merchant country at Payment method backend is United States.
The issue is about “PayPal Payments Advanced (Includes Express Checkout)”method:
We have configured the Payment method : “PayPal Payments Advanced (Includes Express Checkout)”
The result is that only the included PayPal Express Checkout works but the PayPal advance doesn’t .
In checkout page, we can see the PayPal advance radio button option but when we select it and proceed to the next steps as shown in this video [url removed, login to view] ( frame 2:47 onwards ) , ie, after we click “continue” in order review section, it does not display any credit card form, which it is supposed to display.
We have done the following things to fix the issue :
1- We have followed the PayPal Manager configuration at [url removed, login to view] as per instructions.
2- We have followed and ensured proper configuration settings at Magento backend for PayPal.
3- Enabled / Disabled extensions at Admin->Advance, Cleared Cache, re-indexed.
4- Replaced the Core directory with a fresh Magento Core directory of same version
5- Replaced the Base template with a fresh Magento Template of same version
6- We copied the site at another server.
Any of the above did not helped.
Exception log shows this >> exception 'Mage_Core_Exception' with message 'PayPal NVP gateway errors: Security header is not valid (#10002: Security error).
Searching this on web, did not provide clear solution to this error.
Same issue also happened with CRE Secure Payment Gateway. The option appeared, but the credit card form did not show up and this is also remains
At this stage, we need to have your advice or suggestion in order to fix the issue either for PayPal Advance or for CRE Secure.
Please let me know if you have encountered such issue and if this kind of issue can be fixable from your end.
