HTTP 403 (Forbidden)

I am making a website for a school project, and I have a domain and host, and now I'm trying to upload my site. But when I do, I get a message that says HTTP 403 (Forbidden) on my site. Does anyone know why or how to fix this? I am using Frontpage, and I'm told that could be a problem but have had no luck finding a solution. Thank you so much!
