anyone can help me to fix this wordpress errors?

[Becca90]

I just transferred a new WordPress site from my old server to Hostforlife.eu hosting account. The site works fine on my old server. No errors or anything. Once I copied all files to the Hostforlife hosting account though, the homepage displays but with the following errors above it:

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/content/85/10284985/html/wp-content/themes/hcdla/functions.php:1) in /home/content/85/10284985/html/wp-content/plugins/business-directory-plugin/wpbusdirman.php on line 706

When I try to access the admin panel, nothing displays and I get these errors:

I've opened my functions.php file and there are no blank spaces before or after the php. Here is the code though, just in case I am missing something:

PHP Code:
<?php
// Define Menu //
function register_my_menus() {
register_nav_menus(
array(
'top-menu' => __( 'Top Menu' ),
'footer-menu' => __( 'Footer Menu' )
)
);
}
add_action( 'init', 'register_my_menus' );

// Define Sidebars //
if ( function_exists('register_sidebar') )
register_sidebar(array('name'=>'Sidebar One',
'before_widget' => '<div class="widget-col2">',
'after_widget' => '</div>',
'before_title' => '<h2>',
'after_title' => '</h2>',
));

// Force Editor to Use Style.css //
add_editor_style();

// Removes empty paragraphs //
add_filter('the_content', 'remove_empty_p', 20, 1);
function remove_empty_p($content){
$content = force_balance_tags($content);
return preg_replace('#<p>\s*+(<br\s*/*>)?\s*</p>#i', '', $content);
}
?>

Your help is appreciated Thank you!
