On startup I see

Generating RRD graphs…ERROR: Not enough arguments
ERROR: Not enough arguments

and in the Status -> System Logs -> System page there are these entries:

Jan 29 07:24:23 php: : Create RRD database /var/db/rrd/wan-queues.rrd
Jan 29 07:24:23 php: : RRD create failed exited with 1, the error is: ERROR: you must define at least one Data Source
Jan 29 07:24:23 php: : Create RRD database /var/db/rrd/wan-queuesdrop.rrd
Jan 29 07:24:23 php: : RRD create failed exited with 1, the error is: ERROR: you must define at least one Data Source

This is probably carried over from 1.2.1. I reported it in that forum. I haven't checked this has the same cause.
