Hi,
It most probably caused a fatal error due to syntax.

Please remove it and post the complete functions.php on https://pastebin.com/

I will update it for you to avoid any syntax issue.

You have it correctly there.

I need to check if it works in functions.php or we will need bp-custom.php

Will post back later today.

Hi Patti,
I hope I am not too late.
There was an issue in how I used the s2members function.

Here is the updated code

/**
 * Example: Disable MediaPress gallery for S2 members level 0
 *
 * @param bool   $is_active is MediaPress active.
 * @param string $component component name(members, groups,sitewide etc).
 * @param int    $component_id context items id(user id, group id etc).
 *
 * @return bool
 */
function mpp_custom_disable_for_users( $is_active, $component, $component_id ) {
	// only for members component.
	if ( 'members' !== $component ) {
		return $is_active;
	}

	// do not allow zero level to have the gallery.
	if ( function_exists('current_user_is' ) && current_user_is('s2member_level0' ) ) {
		return false;
	}
	return $is_active;
}
add_filter( 'mpp_is_enabled', 'mpp_custom_disable_for_users', 10, 3 );

The current_user_is only takes role not the user id. I installed and tested with s2members today.

Hope it helps.
