Line breaks and paragraphs disappears after publishing page

What is your theme’s page.php using to display the page content?

You mean the code? Is like this:

<?php get_header(); ?>

		<div id="primary" class="grid_8">
			<div id="content" role="main">

				<?php while ( have_posts() ) : the_post(); ?>

					<?php get_template_part( 'content', 'page' ); ?>

					<?php comments_template( '', true ); ?>

				<?php endwhile; // end of the loop. ?>

			</div><!-- #content -->
		</div><!-- #primary -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

Looks like your theme uses the content-page.php template file to output the pages content. You will need to look in that file.

Ok, Thank you for helping.

The content of the content-page.php is this:

<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
	<header class="entry-header">
		<h1 class="entry-title"><?php the_title(); ?></h1>
	</header><!-- .entry-header -->

	<div class="entry-content softShadow">
		<?php the_content(); ?>
		<?php wp_link_pages( array( 'before' => '<div class="page-link">' . __( 'Pages:', 'toolbox' ), 'after' => '</div>' ) ); ?>
		<?php edit_post_link( __( 'Edit', 'toolbox' ), '<span class="edit-link">', '</span>' ); ?>
	</div><!-- .entry-content -->
</article><!-- #post-<?php the_ID(); ?> -->

There’s nothing wrong with that code. <?php the_content(); ?> will output the formatted page content. And given that I’ve used the Toolbox theme, I know that the template works just fine. Have you tried:

– deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).

– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.

Ok. Thank you esmi!

I will try those procedures and let you know!

Is this a child theme or the parent Toolbox theme? If it’s the latter, have you modified the theme in any way?

I have modified the theme.

I have done what you suggested. The very first plugin I had activated seems to be the problem: qTranslate. If it is on, the paragraphs won’t work. If I turn it off… it works…

FIXED! It was a qTranslate plugin bug.

I got the solution from here: https://wordpress.stackexchange.com/questions/42877/qtranslate-2-5-28-and-wordpress-3-3-1-issues/45371#45371

Thank you esmi!
