ACF中的WordPress所见即所得工具栏未显示

Question

我需要有关高级自定义字段（ACF）中所见即所得（WYSIWYG）编辑器的帮助。

工具栏未显示（例如，粗体，斜体，下划线等）

add_filter( 'acf/fields/wysiwyg/toolbars' , 'my_toolbars'  );
function my_toolbars( $toolbars )
{

    // Add a new toolbar called "Very Simple"
    // - this toolbar has only 1 row of buttons
    $toolbars['Very Simple' ] = array();
    $toolbars['Very Simple' ][1] = array('bold' , 'italic' , 'underline' );

    // Edit the "Full" toolbar and remove 'code'
    // - delet from array code from http://stackoverflow.com/questions/7225070/php-array-delete-by-value-not-key
    if( ($key = array_search('code' , $toolbars['Full' ][2])) !== false )
    {
        unset( $toolbars['Full' ][2][$key] );
    }

    // remove the 'Basic' toolbar completely
    unset( $toolbars['Basic' ] );

    // return $toolbars - IMPORTANT!
    return $toolbars;
}

感谢任何意见

谢谢。
