You can try to fix this problem with my solution
Open templates/ja_mero/css/template.css file
From
.ja-mainnav .navbar {
color: #666;
margin-bottom: 0;
margin-top: -40px;
}
.ja-mainnav .navbar-inner {
background-color:Black;
-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";
filter: alpha(opacity=50);
opacity:.5;
filter: progid:DXImageTransform.Microsoft.gradient(enabled=false);
min-height: 40px;
padding: 10px;
border: 0;
-webkit-border-radius: 0;
-moz-border-radius: 0;
border-radius: 0;
-webkit-box-shadow: none;
-moz-box-shadow: none;
box-shadow: none;
float: right;
margin-top: -45px;}
.ja-mainnav .navbar .nav {
margin: 0;
}
Change to
.ja-mainnav .navbar {
color: #666;
margin-bottom: 0;
margin-top: 0px !important;
}
.ja-mainnav .navbar-inner {
background-color:Black;
-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";
filter: alpha(opacity=50);
opacity:.5;
filter: progid:DXImageTransform.Microsoft.gradient(enabled=false);
min-height: 40px;
padding: 10px;
border: 0;
-webkit-border-radius: 0;
-moz-border-radius: 0;
border-radius: 0;
-webkit-box-shadow: none;
-moz-box-shadow: none;
box-shadow: none;
float: right;
margin-top: -85px;}
.ja-mainnav .navbar .nav {
margin: 0;
}
