Fatal Error when visiting any other page on the blog.

Hey everyone.

When I click on a link to another page in my blog, I get the following error:

Fatal error: Call to undefined function php_e() in /home/*****/public_html/HesedBlog/wp-content/themes/hesedblogv2/index.php on line 38

So, I load up my theme in the editor, and take a look at the line of code on line 38. Here she is:

<h2><?php_e('Not Found'); ?></h2>

I looked at some other themes, and they all looked the same.

I am absolutely stumped. The blog looks fine from the index page, you can click on a post just fine, you can view a category just fine, but God help me if I click on a link to another page – I get that error.

If you need it, here’s my index.php code. Thanks to anyone who can help:

<?php get_header(); ?>

<?php get_sidebar(); ?>

<div id="Content">

	<?php if(have_posts()) : ?><?php while(have_posts()) : the_post(); ?>

    		<div class="post">

        		<div id="posttitle"><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></div>

        		<div class="entry">

					<?php the_content(); ?>

                    <p class="postmetadata">

<?php _e('Filed under:'); ?> <?php the_category(', ') ?> <?php _e('by'); ?> <?php  the_author(); ?><br />

<?php comments_popup_link('No Comments »', '1 Comment »', '% Comments »'); ?> <?php edit_post_link('Edit', ' | ', ''); ?>

					</p>

        		</div>

        	</div>

	<?php endwhile; ?>

    	<div class="navigation">
        	<?php posts_nav_link(); ?>
        </div>

    <?php else : ?>

        <div class="post" id="post-<?php the_ID(); ?>">
        	<h2><?php_e('Not Found'); ?></h2>
        </div>

	<?php endif; ?>

</div>

<?php get_sidebar('right'); ?>

<?php get_footer(); ?>

</div>
