Error message

[eluser]Unknown[/eluser]
Hello

I have a problem here whereby I need to run a hotspot application and I keep getting an error that says

Fatal error: Class 'Controller' not found in C:\xampp\htdocs\easyhotspot\htdocs\system\application\controllers\home.php on line 3

now I was just wondering is this a bug cause I haven't done anything to the code.

Thanks in advance
