Solving “headers already sent” warnings

I have completed all of the remedies listed in the Troubleshooting document and cannot resolve this. The Troubleshooting document says there must be no information after the php close (?>), however the flagged file (feed-rss.php) has the following data after that closing tag:

<rss version=”0.92″>
<channel>
<title><?php bloginfo_rss(‘name’); wp_title_rss(); ?></title>
<link><?php bloginfo_rss(‘url’) ?></link>
<description><?php bloginfo_rss(‘description’) ?></description>
<lastBuildDate><?php echo mysql2date(‘D, d M Y H:i:s +0000’, get_lastpostmodified(‘GMT’), false); ?></lastBuildDate>
<docs>https://backend.userland.com/rss092</docs&gt;
<language><?php echo get_option(‘rss_language’); ?></language><?php do_action(‘rss_head’); ?><?php while (have_posts()) : the_post(); ?><item><title><?php the_title_rss() ?></title><description><![CDATA[<?php the_excerpt_rss() ?>]]></description><link><?php the_permalink_rss() ?></link><?php do_action(‘rss_item’); ?></item><?php endwhile; ?>
</channel>
</rss>

This would appear to be a crucial part of this document and I don’t know that this is the problem or not. Meanwhile no one can subscribe to my blog until this is fixed. Any help?

Don’t touch any of the core files. Try looking on your theme’s templates files, your wp-config.php file and any external files that you are using to display posts.

That tells me that you should be looking at your index.php file instead. Probably the first line. Probably you have a blank or a space or something before the beginning <?php code.

esmi – Don’t know what “core files” are. Not using any “external files” to display posts. There are dozens of theme template files – am I looking for spurious spaces or data in each one?

otto – nothing there.

Tried to fix my sight per recommendations and it only made matters worse. Now I can’t get into the admin section. Instead, I get this:

I saved a copy of wp-config.php and restored it when things went wrong, but it didn’t help.

Now I’m dead in the water and can’t update my blog. I have built my own sites before and chose to do this one with WordPress to save myself some time, but these problems have taken me 5 times longer than it would have taken me to build my own site. I’d love someone to help me how to salvage this site but I’m out of answers.

It’s telling you where the error is. It can’t be mistaken on this point.

“(output started at /nfs/c03/h06/mnt/55862/domains/gravityu.com/html/blog/wp-config.php:1”

That means you need to look at your wp-config.php file, line 1.
