I created a Force.com site and linked a Visualforce page with it, but when I access the link I get down for maintenance error page. I am not sure how to get my visual force page instead of this error. I made the force.com website as active too but I still this error page. I saw this help link - https://developer.salesforce.com/forums/?id=906F000000099UQIAY
But I do not know what it means by putting my visualforce in a folder.
