[weewx-user] Caught unrecoverable exception in generator ImageGenerator

2019-09-10 Thread gjr80 
Hi,

Would help to see more of the log in the lead up to the error (so we know which 
skin caused the error). Can you also post the [StdReport] section of weewx.conf 
(you can use wee_debug (http://weewx.com/docs/utilities.htm#wee_debug_utility) 
for this if you want) but make sure you check for any sensitive info before 
posting. Would also like to see the skin.conf for the offending skin but we 
don’t know which skin it is at the moment (unless of course you have only one).

Gary

Hello,

I receive the following error message ( tail -f /var/log/weewx.log / 
Raspberry )

reportengine: Caught unrecoverable exception in generator 
'weewx.imagegenerator.ImageGenerator'
  math domain error

  mag = math.floor(math.log10(steps))
  ValueError: math domain error
  Generator terminated

and I have no idea how to fix it.
