    Yes, I tried that =) it gave me the following error

    We are sorry for the inconvenience. The PayPal account authentication settings are not yet set up, or the API security information is incorrect. We are unable to complete your transaction. Please notify the store owner so they can correct this problem. (10002) 10002 Security error - Security header is not valid

    Your logs aren't showing any "amount" details at all. Unfortunately they're not giving a reason why either.

    Actually, the log that Melanie posted shows an amount of 0.05 (the "total"). Could that be the issue (that the amount is too small)?

    Hi Lat,

    Thanks for looking, but the amount matters none... same result every time. I thought I was seeing some PP issue from the stuff they have had going on for the last few days with late API returns and such, but it persists.

    Dr Byte - any suggestions?

    Okay so maybe there is a bug here.

    I have installed a full vanilla cart with zero addons, nor changes. The demo products are loaded.

    I installed PP Express with PayFlow using the valid creds from the live site and the error persists on my fully Vanilla cart. In fact the only changes at all is to update the my store address etc on install and PP express, I didn't even update the currencies.

    https:// checkoutprofit .com /vanilla/

    If the dev team could take a look, I would appreciate it.

    Would like to add to this that I've had the same error.

    Replacing /includes/modules/payment/paypalwpp.php from v1.5.4-12302014 fixed issue on v1.5.6c-07162019

    The file from v1.5.5-03172016 onwards has the problem

    I am repeating this error on a vanilla install.

    Reverting to previous versions of paypalwpp.php doesn't seem to help.

    has any one had further success?

    My position is that I am using the same set of credentials successfully elsewhere and have confirmed that they are not entered incorrectly. In other words, the problem site is a development version of a live site. Credentials work on the live site and do not work on the development site. I have copied and pasted the settings from Paypal (multiple times) rather than copying settings between the databases.

    With Payflow UK I am getting the invalid amount error - although the amount seems fine ...

    Code:
    Array
    (
        [PAYMENTREQUEST_0_AMT] => 0.47
        [PAYMENTREQUEST_0_ITEMAMT] => 0.47
        [L_PAYMENTREQUEST_0_NUMBER0] => PC-UNTM
        [L_PAYMENTREQUEST_0_NAME0] => Unreal Tournament Linked [22] Version: Download: Windows - English
        [L_PAYMENTREQUEST_0_QTY0] => 1
        [L_PAYMENTREQUEST_0_AMT0] => 0.47
        [PAYMENTREQUEST_0_CURRENCYCODE] => GBP
        [LOCALECODE] => GB
        [GIFTMESSAGEENABLE] => 0
        [GIFTRECEIPTEENABLE] => 0
        [GIFTWRAPENABLE] => 0
        [GIFTWRAPNAME] => 
        [GIFTWRAPAMOUNT] => 0
        [BUYEREMAILOPTINENABLE] => 0
        [CUSTOMERSERVICENUMBER] => 
        [BRANDNAME] => ####
        [PAYMENTREQUEST_0_PAYMENTACTION] => Sale

        [ec_cancel] => 1
        [PAGESTYLE] => Primary
        [REQUEST_ID] => 1570195250
        [USER] => ####
        [PWD] => ####
        [PARTNER] => PayPalUK
        [VENDOR] => ####
    )
    
    
    Response: 
    Array
    (
        [RESULT] => 4
        [RESPMSG] => Invalid amount
        [REQUEST_ID] => 1570195250
        [CURL_ERRORS] => 
    )
    
    
    SetExpressCheckout, Elapsed: 906ms -- Failed
    
    RESULT=4&RESPMSG=Invalid amount&REQUEST_ID=1570195250&CURL_ERRORS=
    Anybody have any thoughts ?
