Can I remove this in the messages?

If you are using the WordPress Default theme you would delete that in wp-content/themes/default/sidebar.php. So you would delete code like this:

<small>
						This entry was posted
						<?php /* This is commented, because it requires a little adjusting sometimes.
							You'll need to download this plugin, and follow the instructions:
							https://binarybonsai.com/archives/2004/08/17/time-since-plugin/ */
							/* $entry_datetime = abs(strtotime($post->post_date) - (60*120)); echo time_since($entry_datetime); echo ' ago'; */ ?>
						on <?php the_time('l, F jS, Y') ?> at <?php the_time() ?>
						and is filed under <?php the_category(', ') ?>.
						You can follow any responses to this entry through the <?php post_comments_feed_link('RSS 2.0'); ?> feed.

						<?php if (('open' == $post-> comment_status) && ('open' == $post->ping_status)) {
							// Both Comments and Pings are open ?>
							You can <a href="#respond">leave a response</a>, or <a href="<?php trackback_url(); ?>" rel="trackback">trackback</a> from your own site.

						<?php } elseif (!('open' == $post-> comment_status) && ('open' == $post->ping_status)) {
							// Only Pings are Open ?>
							Responses are currently closed, but you can <a href="<?php trackback_url(); ?> " rel="trackback">trackback</a> from your own site.

						<?php } elseif (('open' == $post-> comment_status) && !('open' == $post->ping_status)) {
							// Comments are open, Pings are not ?>
							You can skip to the end and leave a response. Pinging is currently not allowed.

						<?php } elseif (!('open' == $post-> comment_status) && !('open' == $post->ping_status)) {
							// Neither Comments, nor Pings are open ?>
							Both comments and pings are currently closed.

						<?php } edit_post_link('Edit this entry','','.'); ?>

					</small>

Thanks for response ??

I m not use the default theme. Im use other theme, but this theme dont have any sidebar.php, his name is sidebar1.php

I deleted the code, but still appears the message ??

Sorry for my english xD

This is the code:

[moderated code]

I meant to say single.php.

Ok, thanks ?? Fixed

Next question xD

-Can I use special characters? “? película” for example.
I can add it somehow?

-And finally. Where I can find the “tags”? Thanks again.

Ok, fixed ??

https://www.digitalmediaminute.com/reference/entity/index.php

having the same problem only my single .php only includes

<?php get_header(); ?>
		<div id="primary-content" class="narrowcolumn">
<?php include (TEMPLATEPATH . '/theloop.php'); ?>
<?php comments_template(); ?>
		</div>
<?php get_sidebar(); ?>
<?php get_footer(); ?>

and so i figure its either going to my loop or comments template.

Heres both.

Loop:

<?php
			/*

				It is a delicate piece of machinery. Be gentle! 

				This structure originally comes from the Great K2 theme: https://getk2.com

	<?php /* Headlines for archives */ if ((!is_single() && !is_home()) || is_paged()) { ?>

	<h2 class="pagetitle">
	  <?php if (is_category()) {
					  printf(__('Archive for the \'%s\' Category', 'rgb'), single_cat_title('', false));
					} elseif (is_day()) {
					  printf(__('Archive for %s', 'rgb'), get_the_time(__('F jS, Y', 'rgb')));
					} elseif (is_month()) {
					  printf(__('Archive for %s', 'rgb'), get_the_time(__('F, Y', 'rgb')));
					} elseif (is_year()) {

					} elseif (is_search()) {
					  printf(__('Search Results for \'%s\'','rgb'), attribute_escape(stripslashes(get_query_var('s'))));
					} elseif (function_exists('is_tag') && is_tag()) {

					} elseif (is_paged() && ($paged > 1)) {

What do u guys think?

also deleted the recommended sections of single.php from the default theme just in case

make a backup copy first

theloop.php:

<p class="intro">

		<?php if (('open' == $post-> comment_status) && ('open' == $post->ping_status)) { /* Both Comments and Pings are open */ ?>
		<?php _e('You can <a href="#respond">leave a response</a>, or ','rgb')?><a href="<?php trackback_url(true); ?>" rel="trackback"><?php _e('trackback','rgb')?></a><?php _e(' from your own site. ','rgb')?>
