PayPal Error Code

[Ker-ching]

Hi,

 

I have two Prestashop projects that I am having the same problem with on the PayPal checkout.

 

Both generate the same error message:

shop 1:

Please refer to logs:

• PayPal response:
  
• TIMESTAMP -> 2012-08-21T15:21:20Z
  
• L_ERRORCODE0 -> 10002
  
• L_SHORTMESSAGE0 -> Security error
  
• L_LONGMESSAGE0 -> Security header is not valid
  
• L_SEVERITYCODE0 -> Error
  
• PayPal returned error
  

 

shop 2:

Please refer to logs:

• PayPal response:
  
• TIMESTAMP -> 2012-08-21T15:29:04Z
  
• L_ERRORCODE0 -> 10002
  
• L_SHORTMESSAGE0 -> Security error
  
• L_LONGMESSAGE0 -> Security header is not valid
  
• L_SEVERITYCODE0 -> Error
  
• PayPal returned error
  

 

The two shops are linked to different PayPal accounts and I have double checked the API code used - in fact I put the same code in a different type of shop and got no error on checkout.

 

I have a number of shops running successfully, but the two I started work on yesterday both generate the same error.

 

Has something changed, or have I become dumb?

 

Any help or suggestions very welcome.

 

Thanks
