Startingdays

I figured out my problem. It was because of my Jetpack Plugin. I deactivated the mobile theme function and now its working.

But thank you for helping me so fast ^_^

Fixed it.

<?php get_header(); ?>
<div id="page">
<!--Inhalt-->
<div id="contentwrapper">

<div id="left-sidebar"><?php include (TEMPLATEPATH . '/sidebar-left.php'); ?></div>

<!--post-->
<?php query_posts($query_string.'&cat=-3&&order=DESC');
while (have_posts()) : the_post(); ?>
<div class="entry" id="post-<?php the_ID(); ?>">
<p class="datum"><span class="content">Posted by: <?php the_author() ?><br />Tag: <?php the_category(', '); ?>
<br />Date: <?php the_time('jS, M, Y') ?></span></p>
<h1><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h1>
<div style="clear:both;"></div>
<div class="entry-content">
<?php the_content(''); ?>
</div>
<div class="commentpost"><a href="http://s803.photobucket.com/albums/yy314/chrissy2504/Startingdays/?action=view&current=comments.png" target="_blank"><img src="http://i803.photobucket.com/albums/yy314/chrissy2504/Startingdays/comments.png" border="0" alt="Photobucket"></a> <?php comments_popup_link('0 Comments', '1 Comments', '% Comments'); ?></div>
</div>
<!--post-end-->
<?php endwhile; ?>   

</div><?php if(function_exists('wp_paginate')) {
    wp_paginate();
} ?>
<div id="right-sidebar"><?php include (TEMPLATEPATH . '/sidebar-right.php'); ?></div></div><!--Inhalt-->
</div>
<?php get_footer(); ?>

and the css to

/* Div Sidebars */
 #right-sidebar {
   overflow: hidden;
   float: right;
   position: absolute;
   left: 913px;
    top: 0;
 }
 #left-sidebar {
	 overflow: hidden;
   float: left;
   position: relative;
   margin-left: 35px;
   display: inline;
    }

Its because I´m using the old css now. The problem is, when you use IE or an other browser, the right sidebar is not in the content.

and when I use the code above it look like this

thank you for helping me. I could fix the problem this morning. A div was too much in my sidebar. Now its working XD
