Fresh installation Parse Error

Hi all,

Does anyone know why the feeds error is happening on fresh install.

Parse error: syntax error, unexpected ‘a_required’ (T_STRING) in /public_html/wp-includes/feed.php on line 454

function rss_enclosure() {
if ( post_psword a_required() )
return;

foreach ( (array) get_post_custom() as $key => $val) {
if ($key == ‘enclosure’) {
foreach ( (array) $val as $enc ) {
$enclosure = explode(“\n”, $enc);

// only get the first element, e.g. audio/mpeg from ‘audio/mpeg mpga mp2 mp3’
$t = preg_split(‘/[ \t]/’, trim($enclosure[2]) );
$type = $t[0];

/**
* Filter the RSS enclosure HTML link tag for the current post.
*
* @since 2.2.0
*
* @param string $html_link_tag The HTML link tag with a URI and other attributes.
*/
echo apply_filters( ‘rss_enclosure’, ‘<enclosure url=”‘ . trim( htmlspecialchars( $enclosure[0] ) ) . ‘” length=”‘ . trim( $enclosure[1] ) . ‘” type=”‘ . $type . ‘” />’ . “\n” );
}
}
}
}

thanks Dayne
