Do you have access to your control panel through your host?
There is a few things that this could be.
A few ideas to find/solve the problem –
1). WordPress isn’t throwing a “404” not found error, which leads me to believe you are missing some includes files from the installation process. You should just be able to upload those files and be alright.
2). If you have access to your database, verify you URL’s are correct in the table.
3). Your site looks empty, like you’re just getting started, I would nuke the Database, remove the files and reinstall everything.
