It won't necessarily help your current issue, but this is why I created
MG_LOG. It lets you configure your output to send it to a screen, change
it format (maybe add a add date/time stamp or routine the MG_LOG
statement was called from), or turn output on/off by levels from
CRITICAL to DEBUG.

Check out a recent post of my site for some more information (before it
goes off into the weeds about a specific issue on subloggers):
