    Ever since I installed a new theme “Newsflash” I’ve been getting these errors. I cannot even logout of wordpress or publish posts.

    I tried deactivating all plugins and that didn’t work.

    Here is the warning when I try to access my feed:
    Warning: Cannot modify header information – headers already sent by (output started at /hsphere/local/home/avermat/musicdaily.org/wp-content/themes/newsflash/functions.php:11) in /hsphere/local/home/avermat/musicdaily.org/wp-includes/feed-rss2.php on line 2

    Here is that file:

    <?php
    header(‘Content-Type: text/xml; charset=’ . get_option(‘blog_charset’), true);
    $more = 1;

    ?>
    <?php echo ‘<?xml version=”1.0″ encoding=”‘.get_option(‘blog_charset’).'”?’.’>’; ?>

    <!– generator=”wordpress/<?php bloginfo_rss(‘version’) ?>” –>

    <?php rss_enclosure(); ?>
    <?php do_action(‘rss2_item’); ?>
    </item>
    <?php endwhile; ?>
    </channel>
    </rss>

    These are the warnings I get when I try to logout of WordPress:

    I’ve been reading all kinds of posts from people with the same problems but I can’t seem to find what’s wrong.

    For me. What is the problem?

    look at this file:

    /home/gasn/public_html/esio.com/wp-content/themes/illacrimo/functions.php

    make sure there are NO space or linebreaks after the closing ?>

    remove the empty line 1 in index.php
