breadcrumbs and Social icons aren't clickable

Hi,
I discovered that the breadcrumbs and Social icons aren’t clickable in my site, they appear but only the first home icon it’s available and works.

At the moment I would like to use this settings only in the portfolio pages but, I tried to active this also in the others normal pages like about me, services… Same issue.
I tried to changed the page settings (Social icon only; breadcrumbs only; both…) same issue.
I tried to change settings in Theme Options> General Options, KO!!!
I deleted the social icons short code but nothing change.
I also searched for a solution in this forum but I have not found.

So, how I can fix the issue?
It could be something related with the permalinks structure?

Thank you
