Hi David,
Thank you for reporting the issue.

If you do not want the close button, Please add the following css .

.mpp-upload-container-close{ display:none;}

You can add it via Appearance->Customize->Additional Css.

As of the unnecessary close button:- It may not suit your theme as they show/hide the form differently, I personally believe it is needed. There are so many themes which don’t do it and there was no way to close the upload area once it opened.

Hi Carsten,
Thank you for using MediaPress.

It seems like some css conflict.

Please share the site and a guest user account. I can check and get back to you quickly.

Hi Frank,
There was an issue with my fix for Nouveau. I missed to check for logged in user.

Here it is updated.

/**
 * Fix for nouveau.
 */
add_filter( 'bp_nouveau_get_members_buttons', function ( $buttons ) {
	if ( is_user_logged_in() || ! isset( $buttons['private_message'] ) ) {
		return $buttons;
	}

	$buttons['private_message']['button_attr']['href'] = wp_login_url( site_url( '?message-redirect=' . bp_displayed_user_id() ) );

	return $buttons;
} );

/**
 * Redirect to the send message when the user logs in
 **/
function buddydev_redirect_to_send_message_on_login() {

//make sure it is our url set in previous step
	if ( ! is_user_logged_in() || empty( $_GET['message-redirect'] ) ) {
		return;
	}

//redirect to PM
	$user_id = absint( $_GET['message-redirect'] );
//let us make sure that user exists
	$user = get_user_by( 'id', $user_id );
//can not PM to invalid user
//also you should not send message to yourself
	if ( ! $user || $user->ID == bp_loggedin_user_id() ) {
		return;
	}

	$url = bp_loggedin_user_domain() . bp_get_messages_slug() . '/compose/?r=' . $user->user_login;

	bp_core_redirect( $url );
}

add_action( 'bp_template_redirect', 'buddydev_redirect_to_send_message_on_login' );

Brajesh
