Unfortunately I do not understand what you mean by…

I’ve removed & nbps from homepage but I’ve the scroll bar issue at the first link of the menu (Studio)

There is no longer a horizontal scroll bar, which is good. I do not see any other issues.

Can you be more specific?

If you are referring to the vertical scroll bar; the page doesn’t have enough content in it to expand beyond your screen size, which is why it doesn’t appear. That is normal.
