Style changed after switched hosting

Hello,

It would be greatly appreciated if anyone can shed me more light on this and tell me how to fix it:

I have a website hosted on hosting1

I replicated it into hosting2

You can see there are difference between the two sites, especially the logo’s size in higher in the new hosting, and the menu’s background color is set to red now.

I believe something is overriding in the new hosting for unknown reason, when I check the menu’s style I can see there are new setting for it which is not in the old hosting:

.top-header-block {
background: red;
}

Why?

Thanks.
