Are you sure that's exactly how the links are rendering on each page? And, for example "MemberPortal.aspx" actually exists in a subfolder named "MembersOnly" (and not in the root)?

In your links this portion POAAEWeb is missing, thus you're getting an error. I suggest to use Request.ApplicationPath to set your paths correctly. But you would need to set them in code.
