HTML is not working anymore

Indeed, it looks like the functions I used to add security validation to the plugin were a bit too extreme and did not allow HTML tags to be used in the plugin’s advanced tab. This has been corrected in version 7.4.2. Please update and fix up these HTMl tags and you should be good. If not, let me know and I will investigate further tomorrow.

If you saved your settings with version 7.4.1, you will need to recreate your HTML configuration under the plugin Advanced Configuration tab, since all HTML tags have been lost.

Can you indicate which tag(s) you were using and in what field?

The tags that are currently allowed in version 7.4.3 are the following:

function allowed_html_tags() {
		return array(
			'a' => array(
				'href' => array(),
				'title' => array(),
				'class' => array(),
				'data' => array(),
				'rel' => array(),
		  	),
			'abbr' => array(
				'title' => array(),
			),
			'acronym' => array(
				'title' => true,
			),
			'b' => array(),
			'blockquote' => array(
				'cite' => array(),
			),
		  	'br' => array(),
			'cite' => array(
				'title' => array(),
			),
			'code' => array(),
			'del' => array(
				'datetime' => array(),
				'title' => array(),
			),
			'dd' => array(),
			'div' => array(
				'class' => array(),
				'data' => array(),
				'style' => array(),
		  	),
		  	'em' => array(),
			'dl' => array(),
			'dt' => array(),
			'em' => array(),
			'h1' => array(),
			'h2' => array(),
			'h3' => array(),
			'h4' => array(),
			'h5' => array(),
			'h6' => array(),
			'hr' => array(),
			'i' => array(),
			'img' => array(
				'alt'    => array(),
			  	'class'  => array(),
			  	'height' => array(),
			  	'src'    => array(),
			  	'width'  => array(),
		  	),
			'li' => array(
				'class' => array(),
		  	),
			'ol' => array(
				'class' => array(),
		  	),
			'option' => array(
				'value' => array(),
				'selected' => array(),
			),
			'p' => array(
				'class' => array(),
			),
			'q' => array(
				'cite' => array(),
				'title' => array(),
			),
		  	'ul' => array(
				'class' => array(),
		  	),
			'select' => array(
				'id'   => array(),
			  	'class' => array(),
			  	'name' => array(),
		  	),
		  	'span' => array(
				'class' => array(),
				'title' => array(),
				'style' => array(),
			),
			'strike' => array(),	  	
		  	'strong' => array(),
		);
	}

Please update to version 7.4.5. All tags mentioned should now be supported.
