Yii, got Exception Error

I got following error, when i use browser extension. But its Working in my localhost. When i upload i got this following error,

[color="#FF0000"]Alias "application.extensions.Browser.CBrowserComponent" is invalid. Make sure it points to an existing PHP file and the file is readable. [/color]

I didn’t understand this error. I don’t know how to solve this problem. Anyone Plz???

Looks like case-sensitive problem. Check the names.

absolutely correct. Thanks a lot
