White button on hover and active pages

Hello All,

I have been trying to get rid of the white overlay when the page is active or when you hover over the button. I have turn off the fancy effect but still will not go anywhere.

Also does any one now how to put the line between each button for example between home and Meet Mosy.

Thank you for all your help in advance
