To hide the author info (written by) on the pages (pages only – not post) I found this post. It wasn’t my template or code but I played with my code similarly to remove both items:

“Open the page.php and delete this line:

<?php _e(‘By’,'themename’); ?> <?php the_author_posts_link(); ?>,
Save your changes, and you are done.”

Mine varied by the following

Removed “Post by” and Date Stamp – following lines of code, (always make copies before changing)…

<span>posted by <?php the_author() ?></span></div>
<div>
<span><?php the_time(‘M’) ?></span>
<span><?php the_time(‘j’) ?></span>

Best to just make a template or 2 to play with before the main page.php
