Function get header Firefox/safari isse

I’ve added a new page template called “Full-width-wide ” that can be selected under page attributes. It renders correctly in chrome but not firefox/safari:

The main-content should be to the right in the nav (not below in firefox).

I’m calling a new header in the full “Full-width-wide” template: <?php get_header(‘wide’);?>

I called a different id “main-wrapper-wide” in the new “header-wide.php file” – this is the only difference. Firefox is still calling the main “header.php” instead of “header-wide.php” – do you know why?

Here’s the CSS I added which it’s calling:

#main-wrapper-wide {

width: 1117px;

margin: 0 auto;

}

#content-wrap-wide {

width: 865px;

float: right;

background: transparent url(images/sidebar-bg-light.png) repeat-y right top;

}
