Dear Meindert Jorna,
For this issue, please follow the steps:

<link rel="stylesheet" href="<?php echo $yt->templateurl().'asset/bootstrap/css/bootstrap-responsive.min.css';?>" type="text/css" />
=>
<!--<link rel="stylesheet" href="<?php //echo $yt->templateurl().'asset/bootstrap/css/bootstrap-responsive.min.css';?>" type="text/css" />-->
Change this code
<link rel="stylesheet" href="<?php echo $yt->templateurl().'css/yt-responsive.css';?>" type="text/css" />
=>
<!--<link rel="stylesheet" href="<?php //echo $yt->templateurl().'css/yt-responsive.css';?>" type="text/css" />-->
2. Open file (\templates\sj_wallblog\css\template.css) add this code:
.container, .navbar-static-top .container, .navbar-fixed-top .container, .navbar-fixed-bottom .container{width:1170px;}
3. Open file (\templates\sj_wallblog\layouts\left-main.xml), find and change:

<group
class="span9 nospacing"
data-normal="span12"
data-stablet="span12"

noleft-data-stablet="span12">main</group>
<group class="span9" data-normal="span9" data-tablet="span9" data-stablet="span9">footer</group>

4. Open file (\tempales\sj_wallblog\index.php) find and delete this code:
<meta name="viewport" content="width=device-width, target-densitydpi=160dpi, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no" />
We will update option responsive as soon as possible.
