Python logging to MemoryHandler initialised in configuration file

I am trying to add the python MemoryHandler into a logging configuration file. I am using a similar structure to a file handler that worked previously. I am a bit confused as to the error I am receiving and can't figure out what I am missing in order to get the logging to go to memory. The necessary information has been included below.In assistance would be greatly appreciated.

log_settings.conf

[loggers]
keys=root

[handlers]
keys=memHandler, consoleHandler

[formatters]
keys=fileFormatter, consoleFormatter

[logger_root]
level=DEBUG
handlers=memHandler, consoleHandler

[handler_consoleHandler]
class=StreamHandler
level=INFO
formatter=consoleFormatter
args=(sys.stdout,)

[handler_memHandler]
class=handlers.MemoryHandler
formatter=fileFormatter
args=(10, DEBUG, '%(logfilename)s')

[formatter_fileFormatter]
format=[%(asctime)s] [%(levelname)8s] --- (%(filename)15s:%(lineno)4s) %(message)s
datefmt=%Y-%m-%d %H:%M:%S

[formatter_consoleFormatter]
format=%(message)s
