Can you access your web folder through the browser?
Can you access the individual pages?
Do you get any errors?
etc..[/quote]

Yes I can access all files in that folder through firefox
Can you access the individual pages? Yes I can
Do you get any errors? There's no error
No display, just empty page, if I call my CI folder which contains a project that already I am working on windows, will be an empty page, if I call any controller, then will empty page also, just white page
