Hi Michael,
Please open file templatesja_wallindex.php and look for this line :
<link rel="stylesheet" type="text/css" href="<?php echo $tplcsspath ?>/layout-normal.css" media="only screen and (min-width:986px) and (max-width: 1235px)" />
<link rel="stylesheet" type="text/css" href="<?php echo $tplcsspath ?>/layout-wide.css" media="only screen and (min-width:1236px) and (max-width: 1585px)" />
<link rel="stylesheet" type="text/css" href="<?php echo $tplcsspath ?>/layout-wide-extra.css" media="only screen and (min-width:1586px) and (max-width: 1890px)" />
then update like below :
<link rel="stylesheet" type="text/css" href="<?php echo $tplcsspath ?>/layout-wide-extra.css" media="only screen and (min-width:1236px) and (max-width: 1890px)" />
<link rel="stylesheet" type="text/css" href="<?php echo $tplcsspath ?>/layout-wide.css" media="only screen and (min-width:1236px) and (max-width: 1585px)" />
<link rel="stylesheet" type="text/css" href="<?php echo $tplcsspath ?>/layout-normal.css" media="only screen and (min-width:986px) and (max-width: 1235px)" />
