Hi @royroy2
No you do not need any code in functions.php.
To fix your code, please call the repeater loop from within the main posts() loop here:
while ( have_posts() ) : the_post(); ?> <!--Because the_content() works only inside a WP Loop -->
<div class="entry-content-page">
<?php the_content(); ?> <!-- Page Content -->
</div><!-- .entry-content-page -->
<?php
endwhile; //resetting the page loop
