Página en blanco al generar pago

[Chelo]

Buenas!!.

 

Tengo un problema en mi tienda al seleccionar una forma de pago (Khipu.com), me aparece la página en blanco al seleccionar este metodo. Activé la consola de errores, pero la verdad es que no entiendo cual es el error. Le dejo lo que me aparece.
