I updated to your new template Wim today
good job Wim
was relatively easy 
I do see one error, might be that my php version 5.5.38 is a bit below minimum, and that is the moon phase script
http://weather-display.com/pwsWD/
Fatal error: Class ‘Moon’ not found in /homepages/22/d75034112/htdocs/weather-display/english/pwsWD/moon_block.php on line 42
I also see Overwegend bewolkt in the current conditions ( I set to use clientraw for that)
