Solar Graph resets on restart of WD

Hi
i am using 10.19s at present but if i have to restart it for any reason the solar graph which may only had say 2000 records before restart resets to zero, also the Evapotranpiration value resets too and in turn this effects the ET on sunshine graph this has happened with recent upgrades as well. this means the ET on sunshine graph is flatter than it should be and the value for yesterday is N/A on the table on web page. it appears not to be saving the values at restart or upgrade using save and exit did not work either.
the only way to get round this is to do restarts or upgrades after the midnight uploads etc are done, this is not always practical.

i have seen the ET problem.,…i will see if i can try and track it down (i have looked before but could never figure it out)
not sure why the solar graph resets before it gets to the max number of records, i will investigate

Hi Brian
i updated WD to 10.19t just after midnight and shortly after the restart the graph reset to zero now some hours later it still says zero records i have it set to update every 60 seconds.
i have just looked at the real time graph (set to 5000 records) and extra real time graphs there records also still say zero as they also reset. the record number only appears to update on graphs at restart.
should they not update each time a graph is opened and should they not reset without restarting the program as they do not appear to at present.
i have seen as much as a weeks worth of graph info to view if i have not had to restart for any reason. using 5000 records ithey all should reset about every 3.5 days. so the 2000 i saw was the figure given at last restart but that could of been 2 or 3 days before so the next restart was over the 5000 and so it reset.
not sure if this is linked to the ET problem but i suspect not hope this helps

Update
just had to do a restart on main unit after copying dat and log file (due to usual console glitch for rain) from backup unit, solar graph and extra real time graphs have reset and both have zero records the real time graph has not reset and has a record count of 2528. the ET has also gone to zero

half hour later had to do the reverse but also updated backup unit to 10.19u this only reset solar graph. the real time and extra real time graphs both have records of 2531

have put 19u on main unit did the same as backup unit
