Duplicate homepage URL

Hello,

My website’s home page logo duplicates the URL – https://infeira.pt/infeira.pt/

It’s a multi-site installation, comprising the main website and an international version https://international.infeira.pt (which works fine).

I also can’t connect JetPack –

“Your Jetpack has a glitch. We’re sorry for the inconvenience. Please try again later, if the issue continues please contact support with this message: home_malformed
The required “home” parameter is malformed.”

So, I think I have some kind of error on the HOME parameters.
Any help would be appreciated!
Thank you
