acosmin

Here you go http://i.imgur.com/2YRudmx.jpg.

The sidebar is where it should be.

So this is not a theme related problem? Please post your questions here: http://wordpress.org/support/forum/how-to-and-troubleshooting

The new update isn’t a problem, I checked and it works fine.

Could you please post a link to your website.

You made some modifications somewhere, because posts shouldn’t be full width (without a sidebar). Only pages have that option…

Which files did you edit?

I am sorry but that is not possible, it will break the layout. You can only move the entire menu to the right (I can give you some pointers if this is what you want).

Then replace:

<a href="<?php echo esc_url( home_url() ); ?>" title="<?php bloginfo( 'title' ); ?>" class="logo-contents<?php ac_logo_class(); ?>"><?php ac_get_logo(); ?></a>

with:

<a href="<?php echo esc_url( home_url() ); ?>" title="<?php bloginfo( 'title' ); ?>" class="logo-contents"><?php _e( 'Your Logo Text', 'acosmin' ) ?></a>

Now open ../languages/en_US.po and at the bottom add:

#. Text in echo
#: simplified/header.php:30
msgid "Your Logo Text"
msgstr ""

If you make these changes, you wont be able to add a image logo.

I am not familiar with qTranslate, I think you can put it in the sidebar.

Open sidebar.php and bellow line 7 add something like:

<aside class="side-box clearfix widget">
  <div class="sb-content clearfix">
    <h3 class="sidebar-heading"><?php _e('Change language', 'acosmin'); ?></h3>
    <?php if (qtrans_getLanguage() == 'en') : ?><?php bloginfo('stylesheet_directory'); ?>/images/logoENG.gif<?php else : ?><?php bloginfo('stylesheet_directory'); ?>/images/logo.gif<?php endif; ?>
  </div>
</aside>

The mini sidebar will show up only if your screen resolution is higher than 1600px (if your screen resolution is smaller, a “Browse More” button appears in the menu bar
