I discovered an error in the Clientraw file. It started after upgrading to the december '19 version (4.2?) Reverting to 4.1 did not help.
I checked my Clientraw.txt file at https://saratoga-weather.org/wdparser/index.php and in line 158, wich should be wet bulb temp the lat.(52.2900000) is shown, wich should be in line 159. The longitude is shown in line 160 instead of 161
The attached screenshot shows the error. It looks like something not too complex to fix. But then again, i could be wrong

Thanks, Gerhard
