the readme.txt explains it
I have flood filter enabled
You make up your own user password by filling in these settings(anything you want), then use the user/password in your cron command
$post_username = ' ';
$post_password = ' ';
Example using cron and CURL with post authentication: (be sure to set 'your_username' and 'your_password' same as in PHP script settings)
00 * * * /usr/bin/curl -d 'username=your_username&password=your_password' http://www.642weather.com/weather/wd-conditions-messenger.php >/dev/null 2>&1
In this example I use user mickey password mouse
$post_username = 'mickey';
$post_password = 'mouse';
Example using cron and CURL with post authentication:
00 * * * /usr/bin/curl -d 'username=mickey&password=mouse' http://www.642weather.com/weather/wd-conditions-messenger.php >/dev/null 2>&1
