[Plugin: Ajax Weather] Undefined error on Chnage

Hi

I’ve just installed this on a site and it looks perfect for what I need. But when I click change I get an error

Fatal error: Call to undefined function get_weather_info() in /####/#####/#/##########/#######/wp-content/plugins/ajax-weather/logic.weather_bar.php on line 28

(I hashed the path for security)

Here is the URL

http://www.local-explorer.com/

Do you have any suggestions?

Thanks

Lee
