When I try to go to index.html after building the pages, it gives me the error:

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, root@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.

It also seems to try to forward me to links.css, because sometimes that seems to end up in the URL. The pages build okay, and I've looked at index.html to make sure it is all there, and it is. This server is pretty new....is there something Web-serverwise that we need to install? Any help will be incredibly useful.

Thanks,
Kari
