Sometimes, you don’t find “kitchen sink” in your WordPress Admin panel.
Most likely, this is due to some conflict with the plugins.
An easy way around to solve this error:
Insert this code into functions.php file:
function unhide_kitchensink( $args ) {
$args[‘wordpress_adv_hidden’] = false;
return $args;
}
add_filter( ‘tiny_mce_before_init’, ‘unhide_kitchensink’ );
(Insert this code into functions.php file.)
– Enjoy!
