Read More link scrolling page

Question

I'm creating a theme, and I want to prevent the page from being scrolled when a user clicks 'Read More' and the code given in the Wordpress Codex is not helping me at all.

My functions.php is exactly the same as the snippet in the Codex and the relevant line of my index.php is:

<div class="content"><p><?php the_content(__('Read More')); ?></p></div>

Edit: I have a new, weird bug: the content of the Codex snippet is being shown as raw HTML in my blog and admin pages.

Answer 1

There is an explanation in the WordPress Codex which I copy here for reference.

Don't forget <?php and ?>

<?php
function remove_more_link_scroll( $link ) {
    $link = preg_replace( '|#more-[0-9]+|', '', $link );
    return $link;
}
add_filter( 'the_content_more_link', 'remove_more_link_scroll' );
?>
