HI Christian,
I am sorry but I am unable to properly understand. Please help me understand it better.

1. Is it happened after the update of MediaPress? If yes, which version of MediaPress are you using currently?

2. Was it working earlier(with older version of MediaPress)?
3. If it is not the above two, which is the update you had done.

4. if it is MediaPress update, Can you please delete MediaPress and reinstall.

5. Please visit Dashboard->MediaPress->Tools and post me the log.

Thank you
Brajesh

Hi Christian,
Welcome to BuddyDev.

Are you using the customizr theme from wp.org? Is it the latest? Please let me know. I will need to download and test in order to assist you.

Thank you

Hi Graham,
Thank you for posting.
Do you mean creating a new plugin for this purpose or using the existing one?

Thank you

Hi,
Please upgrade to 1.1.6 and then you can put the following code in your bp-custom.php

/**
 * Filter wall gallery title
 * 
 * @param string $title name of the wall gallery.
 * @param array  $args {
 *  Context details.
 * @type string $component component name(e.g groups|members|sitewide)
 * @type int    $component_id numeric component id( e.g group id or user id based on the component)
 * @type string $type media type(e.g photo, video,audio, doc etc)
 *
 * }
 *
 * @return string new title
 */
function mpp_custom_wall_gallery_name( $title, $args ) {

	// in this example, we are going to change the title for the groups wall gallery like this
	// <group name> wall gallery.
	if ( 'groups' === $args['component'] ) {
		$title = sprintf( '%s wall %s gallery', groups_get_group( $args['component_id']->name ), mpp_get_type_singular_name( $args['type'] ) );
	}
	return $title;
}
add_filter( 'mpp_wall_gallery_title', 'mpp_custom_wall_gallery_name', 10, 2 );

That will do it.
