 * WordPress version: 3.7.1
    WP e-Commerce version: 3.8.12.1
 * I did this: Using Payment Gateway: Merchant e-Solutions PayHere with Test Mode
   enabled – Filled out billing/contact details, registered user is not required,
   clicked purchase.
 * I expected WP e-Commerce to do this: Allow me to enter billing details and finalize
   purchase.
 * Instead it did this: Printed :
    There was a security error while processing the
   transaction. Please contact the website administrator. Response: invalid_user

 * Sounds possibly like your merchant details are entered incorrectly.
 * Double check your account details with e-solutions
