Cumulus Support

Since upgrading to 3.11.3 my Cumulus MX dashboard does not display any rain data (all fields are showing 0.0, including the yearly and monthly).

Is this a common issue or something broke in my installation?

I am running on Win 7. Upgrade to 3.11.4 did not change anything.

Sounds like you have bad data in your dayfile.txt.
Same issue for your problem with the graphs.

Look in your MXdiags file during the startup phase for references to the lines with problems.

Thanks for the ideas. I checked the MXDiags and there was clear indication in the start-up log of errors. As it turned out, in my dayfile.txt the date was in the different format (/ instead of -) for a few years. i corrected the formats and the problem went away. This solved the historical charts and the rain issue, as well.

Interestingly, the problem with rain showed up only after the 3.11.3.

thanks for the help
