I found a little problem with the theme "revolution". If you create additional page (/admin/pages) with a link to /photo/view/latest, in the database appears references in tables "_menu_item" and "_documets" (like "page_q28aw3ge", null, null, 'photo/view/latest' for example). After that, display the "LAST photos" is not working. I don't know why, didn't have time to test it much. I just deleted this page and references in database. May be this information will be useful to someone, because i spent 4 hours to find problem. :) May be theme not see new page keys... (like base+local_page_title_page_q28aw3ge)/.
