I'm working on a site (http://jennifer.coffeeismagic.com/) and, when I was initially formatting WordPress I didn't want that many features so I stripped out all the <?php get_sidebar() ?> stuff. I realized after the fact that I actually wanted the sidebar on the front page so I stuck that bit of code back in on the archive.php and archives.php files, right where it was before, above get_footer -- to no effect. So I decided to stick <?php get_sidebar() ?> back into the index.php file and when I did that it totally crashed the site, saying "Fatal error: Call to undefined function get_header() in /home/christian_d/jennifer.coffeeismagic.com/index.php on line 1". I didn't change anything other than adding get_sidebar and when I took it back out it still gives me that error. The header.php file is still intact in the same place it was on the server so i don't know what's going on. Any ideas are much appreciated!
Here is the code of index.php:
<?php get_header() ?>
<div id="container">
<div id="content">
<div id="nav-above" class="navigation">
<div class="nav-previous"><?php next_posts_link(__( '<span class="meta-nav">«</span> Older posts', 'sandbox' )) ?></div>
<div class="nav-next"><?php previous_posts_link(__( 'Newer posts <span class="meta-nav">»</span>', 'sandbox' )) ?></div>
</div>
<?php while ( have_posts() ) : the_post() ?>
<div id="post-<?php the_ID() ?>" class="<?php sandbox_post_class() ?>">
<h2 class="entry-title"><a href="<?php the_permalink() ?>" title="<?php printf( __('Permalink to %s', 'sandbox'), the_title_attribute('echo=0') ) ?>" rel="bookmark"><?php the_title() ?></a></h2>
<div class="entry-date"><abbr class="published" title="<?php the_time('Y-m-d\TH:i:sO') ?>"><?php unset($previousday); printf( __( '%1$s – %2$s', 'sandbox' ), the_date( '', '', '', false ), get_the_time() ) ?></abbr></div>
<div class="entry-content">
<?php the_content( __( 'Read More <span class="meta-nav">»</span>', 'sandbox' ) ) ?>
<?php wp_link_pages('before=<div class="page-link">' . __( 'Pages:', 'sandbox' ) . '&after=</div>') ?>
</div>
</div><!-- .post -->
<?php comments_template() ?>
<?php endwhile; ?>
<div id="nav-below" class="navigation">
<div class="nav-previous"><?php next_posts_link(__( '<span class="meta-nav">«</span> Older posts', 'sandbox' )) ?></div>
<div class="nav-next"><?php previous_posts_link(__( 'Newer posts <span class="meta-nav">»</span>', 'sandbox' )) ?></div>
</div>
</div><!-- #content -->
</div><!-- #container -->
<?php get_footer() ?>
