Okay, adding this rule to theme’s style.css (twenty-twelve) seems to have an effect.

.entry-content .treeview .placeholder {
  display:none;
}

However, only the root categories are shown and the child elements (files) do not appear. And when the root category links are clicked, it displays the Not Found page.

[Edit]
Strange, now it does not open the Not Found page when the category links are clicked. It properly displays the child elements. Thank you.

I wonder if it is possible to show the expanded view from the beginning without navigating to child elements.

Yes, to make it 300px x 300px, the following code works. Thanks.

// create custom image size, 80x80 with hard crop
add_image_size( 'fpw_custom_thumbnail', 300, 300, true);

// override the featured image with custom size image
function fpw_custom_featured_image( $featured_image, $featured_page_id ) {
    return get_the_post_thumbnail( $featured_page_id, 'fpw_custom_thumbnail' );
}
add_filter( 'fpw_featured_image', 'fpw_custom_featured_image', 10, 2 );

Adding the style rule seemed not necessary when the image is set to a larger scale by the way.

Also changing the values in the following line in feature-a-page-widget.php worked. But this edits the plugin code so it’s not recommended since it will be gone after an plugin update.
add_image_size( 'fpw_square', 200, 200, true );

Currently setting a custom width and height requires a little bit complicated coding for end users so maybe it’s an good option to consider implemented as an option.

Thanks for the reply, Mark.

I just tried the plugin and indeed the rich text editor appeared in the excerpt field but the result was the same. The widget shows the literal HTML code. I’m using WordPress 3.5.

And for the first time when I tried to save the options of Rich Text Excerpts via the admin page, it threw these errors if that is relevant. It does not throw the errors after that any more.

It seems wp_unschedule_event() and wp_clear_scheduled_hook() cannot delete events without the exact the same argument having passed when they were registered.

I looked into the core and wrote a custom function for it.

function WPUnscheduleEventsByName($strEventName) {

	// this function removes registered WP Cron events by a specified event name.

	$arrCronEvents = _get_cron_array();
	foreach ($arrCronEvents as $nTimeStamp => $arrEvent)
		if (isset($arrCronEvents[$nTimeStamp][$strEventName])) unset( $arrCronEvents[$nTimeStamp] );
	_set_cron_array( $arrCronEvents );
}

The whole sample code.

<?php
/* Plugin Name: Testing Event Schedules */
define("TESTEVENTNAME", 'Sample_Event');

if( !wp_next_scheduled( TESTEVENTNAME ) ) wp_schedule_event( time(), 'twicedaily', TESTEVENTNAME, array('Hello world!'));
register_deactivation_hook(__FILE__, 'Clear_Events');
function Clear_Events() {
	WPUnscheduleEventsByName(TESTEVENTNAME);
}

function WPUnscheduleEventsByName($strEventName) {

	// this function removes registered WP Cron events by a specified event name.

	$arrCronEvents = _get_cron_array();
	foreach ($arrCronEvents as $nTimeStamp => $arrEvent)
		if (isset($arrCronEvents[$nTimeStamp][$strEventName])) unset( $arrCronEvents[$nTimeStamp] );
	_set_cron_array( $arrCronEvents );
}	

add_action( TESTEVENTNAME
			, array(new TestClass, 'Log')	// the method
			, 10	// the priority. 10 is the default
			, 1 	// the number of argument specified in the wp_schedule_event() function
			);	

class TestClass {
	function Log($parameter='') {
		file_put_contents(dirname(__FILE__) . '/log.txt', 'parameter: ' . $parameter . PHP_EOL, FILE_APPEND);
	}
}

However, it is still a mystery that two events are added when activating this plugin. I’d like to make it only a single event being added.

I found a solution by customizing class-bwp-syntax.php.

Around the line number #531, change this code block

extract(shortcode_atts(array(
			'lang' 			=> $this->options['select_default_language'], // assume it is the default lang
			'toggle'		=> $this->options['enable_toggle'], // set to 'yes' or 'no'
			'start'			=> 1,
			'extra'			=> '', // string - list of lines to be double highlighted - e.g. 1,3,5
			'inline'		=> '', // set to 'yes'
			'nested'		=> '', // set to 'yes'
			'parse'			=> 'yes', // set to 'no'
			'strict'		=> '' // set to 'yes'
		), $atts));

to

extract(shortcode_atts(array(
			'lang' 			=> $this->options['select_default_language'], // assume it is the default lang
			'toggle'		=> $this->options['enable_toggle'], // set to 'yes' or 'no'
			'start'			=> 1,
			'extra'			=> '', // string - list of lines to be double highlighted - e.g. 1,3,5
			'inline'		=> '', // set to 'yes'
			'nested'		=> '', // set to 'yes'
			'parse'			=> 'yes', // set to 'no'
			'wlw'			=> '', // set to yes
			'strict'		=> '' // set to 'yes'
		), $atts));

This adds a custom shortcode parameter “wlw”

Insert the following code around the line #574.

if ($atts['wlw'] != '') {
			$content = strip_tags($content, "<br><br /><br/>");
			$content = str_replace(array("<br>", "<br />", "<br/>"), PHP_EOL, $content);
		}

When posting an article, enclose the code with [code wlw=”yes” lang="php"] ...code...[/code] (“codes inside [code] shortcodes." in the Parse Options has to be enabled via the admin panel.)
