When you go into your theme settings, on the WordPress dashboard for your site, you need to click onto the filters tab.
By default the following code will be present:
<span class=”small”>By</span> [post_author_posts_link] <span class=”small”>on</span> [post_date] <span class=”small”>in</span> [post_categories before=””] [post_comments]
Delete the above and save your settings.
This will now allow no post author or date to be shown when displaying articles.
(The above was good for us on a Canvas Theme).
(the above was for removing how many items tto display and the sorting tool)
