can't log into wordpress!

[astridca]

Hello all,

I recently switched the theme with which I was working from default to classic. I edited some of the php/css in the template, and I kept getting funny messages when I did it. Now, all of a sudden, every time I try to log in, it gives me messages not unlike the ones that I kept receiving:

• Warning: Cannot modify header information - headers already sent by (output started at /home/astridca/public_html/wp-content/themes/classic/functions.php:19) in /home/astridca/public_html/wp-login.php on line 287

I cannot access the blog to make changes. I tried going into my CPanel, into the functions.php file, but I still did not understand what is causing the issue at hand.

Does anybody have an idea as to what the problem might be? Please help!

Try going to wp-content/themes/classic and open your functions.php page for editing. Erase everything on that page and copy and paste this into it, then save:

<?php
/**
 * @package WordPress
 * @subpackage Classic_Theme
 */

automatic_feed_links();

if ( function_exists('register_sidebar') )
	register_sidebar(array(
		'before_widget' => '<li id="%1$s" class="widget %2$s">',
		'after_widget' => '</li>',
		'before_title' => '',
		'after_title' => '',
	));

?>
