Dear nsarode!
Please open the file: /templates/ja_mesolite_ii/css/ja.vm.css and find code as following:
a.mainlevel {
display: block;
outline: none;
padding: 8px 15px 9px;
margin: 0;
text-decoration: none;
text-transform: uppercase;
color: #666666;
border-top: 1px solid #E6E6E6;
background: url(../images/arrow.png) no-repeat 92% 14px;
}
and replace:
a.mainlevel {
display: block;
outline: none;
padding: 8px 15px 9px;
margin: 0;
text-decoration: none;
text-transform: none!important;
color: #666666;
border-top: 1px solid #E6E6E6;
background: url(../images/arrow.png) no-repeat 92% 14px;
}
