Estoy intentando actualizar un proyecto de Django 1.5.5 a Django 1.6, sin embargo, he estado recibiendo este error en todas partes.

Traceback (most recent call last):

TransactionManagementError: Your database backend doesn't behave properly when autocommit is off. Turn it on before using 'atomic'.

He eliminadoTransactionMiddleware desdeMIDDLEWARE_CLASSES y lo reemplazó conATOMIC_REQUESTS = True. (Mismo error incluso si no hago este paso)

¿Alguien puede arrojar algo de luz sobre esto?
