Increasing Upload Size

I am wanting to increase the upload size for files to be able to use the Simple Podcasting Plug In and easily host audio files. I followed the directions out lined at https://generatepress.com/forums/topic/image-7mb-uploading-http-error/ and made sure that the server will handle the larger size.

I have placed in the code to functions.php as seen below

/**
* GeneratePress functions and definitions
*
* @package GeneratePress
*/

@ini_set( 'upload_max_size' , '210M' );
@ini_set( 'post_max_size', '200M');
@ini_set( 'max_execution_time', '500' );

// No direct access, please
if ( ! defined( 'ABSPATH' ) ) exit;

However I am still limited to 64MB. Is there a step I missed?

Thanks
