include_once($wxdir . 'CUTags.php');
$uomTemp = '°F';
$uomWind = 'mph';
$uomBaro = 'in';
$uomRain = 'in';
On your CUTags.php. It "should" be CUtags.php. This could be the issue.
Edit: Unless you re-named it.
renamed it.. should this be changed from advforecast.php to CUTags.php??
$wxdir = '../'; // path to the advforecast2.php
This is what mine look like:
include_once($wxdir . 'CUtags.php');
$uomTemp = '°F';
$uomWind = 'mph';
$uomBaro = 'in';
$uomRain = 'in';
Also my settings are:
// --------------- settings ----------------------
include ("Settings.php");
$tweetWXdir = './';
$wxdir = '/home/sacrey/www/www/'; // path to the advforecast2.php
$tweetTags = '#ARwx'; // customize for your Twitter tags and/or website url (shortened)
// ----------- end settings ----------------------
