Continue reading link error

I have built a site using the Clear Styles 1.2 theme. I chose the theme because it is clean and clear.

However, upon getting the site together I have found that there is a … continue reading … function that is broken. Eg when a reader clicks on a post to go to read it in full or make a comment it brings up a non-functioning …continue reading …

This is the code from functions.php – what changes should I make?

function clearstyle_excerpt_length($length) {
    return 40;
}

add_filter('excerpt_length', 'clearstyle_excerpt_length');

function clearstyle_continue_reading_link() {
    return ' <a href="' . get_permalink() . '">' . __('Continue reading', 'clearstyle') . '</a>';
}

function clearstyle_auto_excerpt_more($more) {
    return ' …' . clearstyle_continue_reading_link();
}

add_filter('excerpt_more', 'clearstyle_auto_excerpt_more');

function clearstyle_custom_excerpt_more($output) {
    if (has_excerpt() && !is_attachment()) {
        $output .= clearstyle_continue_reading_link();
    }
    return $output;
}

add_filter('get_the_excerpt', 'clearstyle_custom_excerpt_more');

Or am I looking in the wrong place?
