I’ve noticed 2 errors on my page.
First one - when I open my page (www.mhr-evo.pl) on FireFox there is an empty space at the end of the page (bottom). I’ve checked forum for answer, and I did found an answer - to change Template to “Front Page”. But my page was already on “Front Page”…
Second one - I’ve noticed that when I scroll down my page, there is problem with testimonials widget - it looks like background image is not scrolling properly (see-through from background).
