Looking at your testtags.php?sce=view shows $stationlatitude = ' : : '; // Latitude (from the sun moon rise/set setup)
$stationlongitude = ' : : '; // Longtitude (from the sun moon rise/set setup)
which shows you've not entered your latitude and longitude into WD so it thinks you're at 0,0 .
Use Weather-Display, Control Panel, Sun/Lunar Coordinates TAB
Enter your latitude and longitude there. NOTE: don't use a - (minus) sign for Longitude. The Longitude is astronomical (+ = WEST of GMT), not terrestrial (- = WEST of GMT).
For example, my station here in Saratoga, CA, USA has $stationlatitude = '037:16:28'; // Latitude (from the sun moon rise/set setup)
$stationlongitude = '0122:01:23'; // Longtitude (from the sun moon rise/set setup)
(notice the 122 is NOT -122.
Then WD should correctly compute sun/moon rise/set info for you.
