There is something wrong... It seems that you have badly commented the original line in:
//<?php responsive_post_meta_data(); ?>The right way to comment is:
<?php //responsive_post_meta_data(); ?>If I am right, then we must restart the first test... but let's forget the first way and do it like this:
<?php
echo 1;
echo home_url();
echo 2;
echo home_url('?p=332');
echo 3;
echo get_permalink();
echo 4;
echo get_the_time();
echo 5;
echo get_the_date();
echo 6;
echo get_the_author_meta( 'ID' );
echo 7;
echo get_author_posts_url( get_the_author_meta( 'ID' ) );
echo 8;
echo get_the_author();
?>If I am wrong, then it means that there is some code between
<div class="post-meta">and the line we are replacing, which should not be there.
