    $amount = count($clean) - 1;

    $output = $prefix;

    for ($i = 1; $i <= $amount; $i++) {
        $cleaner = explode("</content>", $clean[$i]);
        $output .= $tweetprefix;
        $output .= $cleaner[0];

Answer 2

Los más probable es que su función the_twitter_feed()es echo resultados en lugar de returning ellos.
