Hello Augus,

It seems that the theme you are trying to use uses a deprecated API. Open the start.php of your theme and replace extend_view() with elgg_extend_view().

Check the Elgg Docs: http://learn.elgg.org/en/1.9/guides/themes.html?highlight=elgg_extend_view

hello too , i'm try look at start.php but elgg_extend_view() has to use

default from my theme FB 

    
    //@todo report some of the extra patterns to be included in Elgg core
    elgg_extend_view('css/elgg', 'facebook_theme/css');
    elgg_extend_view('js/elgg', 'js/topbar');

my be like this but this default from theme not i change....tanks before ..:)
