Hello,

Please replaces the code with this one:

body .whb-color-dark .navigation-style-default .item-level-0:hover > a{
color:#333333;
opacity:0.8;
}

You can enable the collapse widgets in the footer in the Theme Settings > Footer.

In order to clear the sidebar in the Account page, remove all the widgets in the Appearance > Widgets> My Account page sidebar.

Best Regards
