Help with counter

so I recently installed ChCounter widget, now I don’t know how to set it up.

There is an option saying “chCounter Path”, so I put in some path, but then when I insert the widget to sidebard, it wont work. It gives me an error:

CHCOUNTER ERROR
Could not find the chcounter installation. Please check your settings.

Help me please, or if have a counter that can display Visitors today, visitors yesterday, page views etc.. please link me ;D
