Mouse-over link info and multiple domain hosting

Hi all!

I’m having an issue. This is the situation:

I have hosting through GoDaddy. Recently I bought a second domain and as I have the multiple domain hosting plan, started hosting there.

What GoDaddy said to do was create a folder on mine so I did. My main site is https://www.bookofcowan.com and my second site, https://www.realmofbookspodcast.com, is hosted on bookofcowan.com/robp/

The problem I’m having is that when you you are on the Realm of Books website and hover your mouse over a link, it shows the file as bookofcowan.com/robp/whateverItsNameHere.

What I’d like to do is either mask it so it says realmofbookspodcast.com/whateverItsNameHere or simply turn off the ability to show see the bookofcowan.com part. Like, so mouseover doesn’t give away that it’s a subdomain of sorts.

I’m new to all this stuff and any help would be appreciated. Or if anyone here uses GoDaddy and knows how I can host ROBP outside of a folder on bookofcowan that’d be great too. Thanks for your time and any feedback!
