Problem: 2015yearlyreport.htm does not include December

In /wdisplay/webfiles/November2015.htm, under ‘Averages and extremes’, the rain total for the year up til that point: 709.2mm.
In /wdisplay/webfiles/December2015.htm, under ‘Averages and extremes’, the rain total for the year up til that point: 742.2mm.

In /wdisplay/webfiles/2015yearlyreport.htm, the grand total for rain in 2015: 709.2mm.
So it would seem the rain grand total for 2015 does not include December. This gives the impression that no data from december is taken into account whatsoever.
The timestamp for /wdisplay/webfiles/2015yearlyreport.htm though, is 2015-12-31 23:55.

How can I make/force WD /wdisplay/webfiles/2015yearlyreport.htm to recalculate, and include December as well?

you are right, it has not updated at the end of the year
I will look into what can be done to force an update

you should be able to recreate it this way:
in WD go to view, av/ext
then change the year to 2015 and click on year to date
then copy/paste the data in the lower screen into the 2015yearlyreport.htm and re upload that to your web site

So this is a known bug. I see.

This works. Thx!
