* Hello,
* can you please help me with clearing errors for W3 validation.
* After putting your code:
* function pb_the_content_shortcode_fix($content) {
$array = array( ‘[‘ => ‘[‘,‘]
’ => ‘]’, ‘]‘ => ‘]’, ‘]‘ => ‘]’ );
* return strtr($content, $array);
} add_filter(‘the_content’, ‘pb_the_content_shortcode_fix’);
* I still have these errors:
* there is no attribute “role” on
…arter ezcol-last”>
* there is no attribute “aria-controls”
…rdion-title” role=”tab” aria-controls
=”accordion-1-c1″ aria-selected=”false”
* there is no attribute “aria-selected”
…ntrols=”accordion-1-c1″ aria-selected
=”false” aria-expanded=”false”>
* and so on.
* Thank you in advance.

* Can you post the shortcode you are using for each accordion group? It looks like
you may just be using some duplicate HTML in addition to the accordion shortcodes.
