I cant see my sidebar

You also can’t see your footer.
Edit the “main template” (aka index.php) in the theme editor and make sure the last lines are

<?php get_sidebar(); ?>

<?php get_footer(); ?>

That will take care of the sidebar and footer, but you seem to be missing

<div id="content" class="narrowcolumn">

from your main template also.

there is a index php code- https://paste.php.lv/2608

In there is a <?php get_sidebar(); ?>

<?php get_footer(); ?> and <div id=”content” class=”narrowcolumn”> but i cant see my sidebar!

What plugins are you using?

comment_analysis, browsniff, most-commented, post count
