Link in post combines with post url

I put a link in this post… https://lindaburrow.com/2013/07/31/004-new-orleans-skyline-at-dusk/

The link reads:
Prints are available here.

After saving and reloading, that link takes me to an OOPS page with this address:
https://lindaburrow.com/2013/07/31/004-new-orleans-skyline-at-dusk/fineartamerica.com/profiles/linda-burrow.html?tab=artwork

As you can see, it combines both the post url and the link url into one url that doesn’t work.

Can someone help?
Oh, and the link color is black not blue, if that’s any indication of anything.

Thanks.
