I have upgraded theme and nopcommerce to 2.80 version. But when i run the site theme is not applying. Menu background is not coming in red color. And when i check using firebug, i found that there is one "headermenu" class in custom.css file because of which the background color is set as red. Its like below.
background: -moz-linear-gradient(center top , #E41C21 0%, #B20405 100%) repeat scroll 0 0 transparent;
border-radius: 4px 4px 4px 4px;
I am not able to find this class in my 2.80 gift theme custom.css file.
Please Help me in this.
