<?php
	the_content(); // this is your standard way to output Post or Page content
	// now the test
	$var_content = get_the_content();
	echo $var_content;
?>

It looks like paragraphs and break rules (<p> and <br />) are gone. Maybe some other tags too but I have noticed those two. I suppose not so many developers use get_the_content() function, however some of my themes (this one too) needs it in order to extract images or documents out of Post/Page content and still keep text formatted. We all know that the_excerpt() function will strip down each and every html tag so there’s no sense in using it, especially not in Post/Page details template.

Solution

It’s true there’s a solution at codex.wordpress.org but for those who have hard time to find it – here it is:

<?php
	the_content(); // this is your standard way to output Post or Page content
	// now the test which works
	$var_content = get_the_content();
	$var_content = apply_filters( 'the_content', $var_content );
	$var_content = str_replace( ']]>', ']]>', $var_content );
	echo $var_content;
?>

It should be OK now. Just wanted to pay your attention to this issue since WordPress developer team didn’t fix it until 2.8.4 – currently available for download. Maybe next time.
