Probably you forgot to unzip as the current version on your server https://www.weather911.net/pwsWD/w34_livedata.php?sce=view does not has the change from the zip.
Your current version:
$weather["temp_trend"] = $wd[143]; // -1/0/1
the new version when you unzip it
$weather["temp_trend"] = (float) $wd[99] - (float) $wd[90]; # 2019-01-22 replace [143] which is login not value
IMPORTANT When you want support it is common decency to include a link to your site. Poeple who want to help have to see what is happening in the scripts.
So would you be so kind to include the link to your site in your avatar-block. That is the the block on the left of every post you do. The small globe should lead to your index.php If there is a specific page you want to discuss about, always supply the full link.
Most persons on this forum are not clairvoyant, sadly.
