This is what I see in my editor:

// Youtube Code

define(“YOUTUBE_WIDTH”, 425); // default width
define(“YOUTUBE_HEIGHT”, 344); // default height
define(“YOUTUBE_REGEXP”, “/\/”);
define(“YOUTUBE_TARGET”, ” “);

function youtube_plugin_callback($match)
{
$tag_parts = explode(” “, rtrim($match[0], “]”));
$output = YOUTUBE_TARGET;
$output = str_replace(“###URL###”, $tag_parts[1], $output);
if (count($tag_parts) > 2) {
if ($tag_parts[2] == 0) {
$output = str_replace(“###WIDTH###”, YOUTUBE_WIDTH, $output);
} else {
$output = str_replace(“###WIDTH###”, $tag_parts[2], $output);
}
if ($tag_parts[3] == 0) {
$output = str_replace(“###HEIGHT###”, YOUTUBE_HEIGHT, $output);
} else {
$output = str_replace(“###HEIGHT###”, $tag_parts[3], $output);
}
} else {
$output = str_replace(“###WIDTH###”, YOUTUBE_WIDTH, $output);
$output = str_replace(“###HEIGHT###”, YOUTUBE_HEIGHT, $output);
}
return ($output);
}
function youtube_plugin($content)
{
return (preg_replace_callback(YOUTUBE_REGEXP, ‘youtube_plugin_callback’, $content));
}

add_filter(‘the_content’, ‘youtube_plugin’,1);
add_filter(‘the_content_feed’, ‘youtube_plugin’);
add_filter(‘comment_text’, ‘youtube_plugin’);
add_filter(‘the_excerpt’, ‘youtube_plugin’);

Thanks for your help!

* go into the html mode of your editor in WP
* delete the p tags around the [site id]

This problem only began after the most recent WP update.
