Errormessage in nexgen-gallery when trying to click on page 2, 3, 4….

I receive the following error-message, when i try to click on page 2:

Default Gallery Type Template

This is the default gallery type template, located in:
/www/htdocs/w00d28dd/wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/nextgen_gallery_display/templates/index.php.

If you’re seeing this, it’s because the gallery type you selected has not provided a template of it’s own.

How can i fix this?
