Logo imagelinked not correctly to home

Hi there
My logo image points to http://clandecima.it/wordpress (it refers 404 error) instead of pointing to http://clandecima.it
I searched for css to address the issue but I found nothing.
Anyway I can change the url where image points??

I have another question
I saw in CSS there is a way to change border colors of the page builder boxes. They are really light on a white backgroud, so they are really hard to see. Wich css class I have to edit to make boxes colors like black?
