This occurs using the Pin Payments payment gateway, using the Test API keys and no SSL.

It goes to white screen of death after the 'confirm checkout' screen during the 5 step checkout process.

I run debug, and the white screen is outputting the above errors.

Will notify the guys at Pin also.

Can this be looked into asap as I have a client waiting for this.

Cheers,

Johnny
