The following error is generated in sandbox (test) checkout.
Please correct the following errors in the form fields below:
- CIVICRM_CONTRIBUTE_PAYMENT_KEY is not set in the config file.
Google checkout is enabled and running CiviCRM 1.7.
In the global payment setting Google checkout is set and parameters are assigned to the relevant values.
In the civicrm.settings.php file 'CIVICRM_CONTRIBUTE_PAYMENT_TEST_KEY' is also set manually to Google merchant key.
Unlike the environment in sandbox.civicrm.org my version does not have a setting option in the administrator interface to configure CIVICRM_CONTRIBUTE_PAYMENT_TEST_KEY so did manually as outlined in the installation instruction.
