if you can post some code that you have written, it will give us an idea of if anything needs to be changed.
One of the problems with web designers here is that in building a website with absolute path's when relative path's should be used.
Example, an absolute path would be http://www.domain.com/Path/to/your/file/filename.html and a relative path would be /Path/to/your/file/filename.html
some web design tools will automatically put an absolute path in any features that have a URL, which can cause problems when uploading to server.
another area that causes problems is where you'll development environment has a different file structure to that of the service and any scripts like PHP have references that are themselves absolute paths, so any scripts you rely on but also need to be looked at.
