Domain help, stuck on file directory

Hi,

my domain name is https://www.dantanton.com. When I visit the domain I am sent to a file directory page ‘Index of’ (I think that’s the correct name!) which has two links ‘cgi- bin’ and ‘wp’. When ‘wp’ is clicked, I am taken to my wordpress site.

How do I get https://www.dantanton.com to go my wordpress site without that file directory page?

Have I done something wrong during set up, or have I just missed a step?

Thanks ??
