Wordpress - Stop editor from removing <p> tags and replacing them with nbsp
I have done extended research and found the answer - I am now using a hook on 'tiny_mce_before_init'.
Based on other answers (special thanks to answer #2 @Chip Bennett), I have used the following code in my functions.php to secure the paragraph breaks (in the editor HTML mode they show as   but become paragraphs on the front-end):
function tinymce_config_59772( $init ) {
// Don't remove line breaks
$init['remove_linebreaks'] = false;
// Convert newline characters to BR tags
$init['convert_newlines_to_brs'] = true;
// Do not remove redundant BR tags
$init['remove_redundant_brs'] = false;
// Pass $init back to WordPress
return $init;
}
add_filter('tiny_mce_before_init', 'tinymce_config_59772');
You can find on the tinyMCE site the different possible configurations.
