Hi Mikee,

Are you using the DPS method as payment? Either or - I experienced this problem once because of the settings in the mysite/_config.php file.

If your DPS account is in test mode - you must set your site to development mode by putting the following code in your config file:

// Set's what environment the site is in (dev,test,live)
Director::set_environment_type('dev');

And then you will need to use the following code if you are using DPS (if your DPS account is in Test mode)

// Check if the site is in 'live' mode, use the live credentials.
// otherwise, use test credentials instead to be careful.
if(Director::isLive()) {
   DPSPayment::set_account('', '');
} else {
   DPSPayment::set_account('UserNamedev', 'yourdetails');
}

Hope this helps!
