Cannot access website (files in a folder); but can access from local machine

Hi,
I can run my Employer website in my local machine when I run it from the visual studio.
But, I uploaded the site now. I can access all aspx pages except the pages in 'Employer' folder.
Employer folder should be accessed by Employer and Administrator roles. I already set those roles in my ASP.NET Administrator tool. When I try to login as an Employer and try to access the pages like ~/Employer/Default.aspx, I can't access them. I can access them when I run it in  my local machine from Visual Studio. I don' t find any error in my database. Any idea.
Thanks
