ESP Posted February 28, 2014 Share Posted February 28, 2014 (edited) Hi I have installed the EU paypal module, and configured it with my Paypal API details which all seemed to go OK. When i go to check out I get the following error : Please try to contact the merchant: <b>PayPal response:</b> TIMESTAMP -> 2014-02-28T07:34:08Z L_ERRORCODE0 -> 10002 L_SHORTMESSAGE0 -> Security error L_LONGMESSAGE0 -> Security header is not valid L_SEVERITYCODE0 -> Error I've contacted Paypal who say they are going to look into it for me however does anyone else know what the issue may be ?

Joel Bardsley Posted March 1, 2014 Share Posted March 1, 2014 (edited) Hi, I had this happen once when configuring the paypal module for a UK shop. The answer is the PayPal API password has probably been entered incorrectly into the field on the module's configuration page.. Even if you've copied and pasted it, it might have missed something off the end of it. The one in my example had .xxx appended to the end of it, which had got left out when first copying+pasting. Hope that helps. Joel Edited March 1, 2014 by Joel Bardsley (see edit history) Link to comment Share on other sites More sharing options...
