Profile in blank

Hello!
I was exactly looking an option like this for my website’s profile! I wanted to add a field for “favorite genres” and link to post’s tag.
I made the same thing in the tutorial, but when I add a relationship in the settings ( fav_genres|tax|tag|true ) click on save and go to check the profile, all becomes blank… If I remove the relationship it returns to normal.

Here is an screenshot of how it looks like. Not even the header or the menus showing…

Am I making something wrong?

Thank you in advance
