Navbar Color changes to White while Page Loading

[Impromptu]

Hi there,

Wondering whether anyone can help me?

The Navbar (private message, FAQ, Calendar, Community etc) has the correct background color, however while refreshing/loading, the background color changes to White and just when the page loads it changes to the correct color.

I presume it's the alternate color, but I'm not sure.

Note the Navbar background color is correct, it just changes while the page loads.

Thanks

Jay
