Put a functions.php file to your theme folder
With the content
<?php
if ( function_exists(‘register_sidebar’) )
register_sidebar();
if ( function_exists(‘register_sidebar’) )
register_sidebar(array(
‘before_widget’ => ‘<div id=”%1$s” class=”widget %2$s”>’,
‘after_widget’ => ‘</div>’,
‘before_title’ => ‘<div class=”widget-title”>’,
‘after_title’ => ‘</div>’,
));
?>
This may help You. BTW quotes on Daydreamz are awesome.
previous_posts_link() Does the same thing but It displays only the links to previous and next pages
There may be a chance that only the files in your ftp account are lost and database is still alive.
Login to your php myadmin to see if its undamaged or damaged.
