Some days ago I have the problem at http://www.meteomaspalomas.com/. I have seen that the version of weatherdisplay (10.37S83) into clientrawextra.txt is " 17:15 85 28 19:24 22:32 12.2 - 6.1 15:26 - - 17.6 1.4 16:50 22:32 - !!E10.37S!! .
shows the data in clientrawextra.txt for ‘Yesterday’ is all missing (shown as - ) starting at field 767
Those should contain values… are you running Weather-Display all the time … I think those figures are filled in only once a day just after local midnight.
Compare to mine at WD Clientraw parser and mine are all filled in starting at field 767.
That just forcibly kills the WD process which is nothing like doing a controlled “Save and Exit”. IMHO all bets are off if you are doing that twice a day 8O
