Logo link not working

Hi,

I seem to have a problem on pages, where I have a portfolio.
When I try to click on the logo of the page,
it usually takes me back to the homepage.
But on pages, where I have a portfolio active,
the logo doesn’t work. Instead it’s trying to open up a lightbox.
Can I fix this somehow?

Thank you,
Laszlo Zadori
