White Bar in Middle of Page

Hello!

I am building a site for a client using this amazing theme and have been stumped for days as to why I have a white bar across the center of all of my pages except my front page. Making changes to individual pages doesn’t eliminate it and I have removed each section of CSS individually and updated just to find no success. I am not using a Child Theme. Any help?

Here is the front page: https://www.rkausa.com
and here is an individual page: https://www.rkausa.com/insurance-services

Below is the code I have in the Custom CSS section.

‘.page .entry-title {
display: none;
border-bottom: transparent !important;
}?

header.tc-header {
background:-color: #fafafa;
border-bottom: transparent !important;
}

.round-div {
border-color: transparent;}

.navbar .nav > li > a, .navbar .nav > li > a:first-letter,
.navbar .nav > li.current-menu-item > a,
.navbar .nav > li.current-menu-ancestor > a {
display: inline;
color: #D90000;
font-family: Open Sans;
font-size: 1.2em;
text-transform: uppercase;
border-bottom: transparent !important;
}

body {
background: url(https://rkausa.com/wp-content/uploads/2015/03/Purple-Backgrond.jpg) repeat 0 0 ;
}

#main-wrapper {
margin-top: 50px;
margin-bottom: 650px;
color: #D0D2D3;
}

.nav {
padding: 10px 35px 5px 16px;}

.navbar .nav > li > a, .navbar .nav > li > a:first-letter {
color:#5d5d5d;}

.navbar .nav > li > a:hover, .navbar .nav > li > a:hover:first-letter
{
color: #FFF;
text-shadow: #303174 0 0 10px;}’
