Hello Just a Short question,
i installed the plugin but get no output. In the back end i see that there is a large index but if i use the search from i get no output. Any Ideas how to solve?

PS: the search on portfolio items in the backend is also not working somehow.

    if($themeple_config['current_sidebar'] == 'fullsize')
        $spancontent = 12;
    else
        $spancontent = 9;
$themeple_config['current_view'] = 'blog';
get_header();
           $id = themeple_get_option('blogpage');
