BLOG not showing in Safari and Firefox

On further inspections i have found “dudes” code and gave it a shot. It worked, but what was the problem ?

add_filter(‘avf_registered_post_type_array’, ‘avia_remove_bbpress_post_type_options’, 10, 2);
function avia_remove_bbpress_post_type_options($post_type_option, $args)
{
if(!empty($post_type_option))
{
foreach($post_type_option as $key => $post_type)
{
if($post_type == ‘forum’ || $post_type == ‘topic’ || $post_type == ‘reply’)
{
unset($post_type_option[$key]);
}
}
}

return $post_type_option;
}

add_filter(‘avia_masonry_entries_query’, ‘avia_remove_bbpress_post_type_from_query’, 10, 2);
add_filter(‘avia_post_grid_query’, ‘avia_remove_bbpress_post_type_from_query’, 10, 2);
add_filter(‘avia_post_slide_query’, ‘avia_remove_bbpress_post_type_from_query’, 10, 2);
add_filter(‘avia_blog_post_query’, ‘avia_remove_bbpress_post_type_from_query’, 10, 2);

function avia_remove_bbpress_post_type_from_query($query, $params)
{
if(!empty($query[‘post_type’]) && is_array($query[‘post_type’]))
{
foreach($query[‘post_type’] as $key => $post_type)
{
if($post_type == ‘forum’ || $post_type == ‘topic’ || $post_type == ‘reply’)
{
unset($query[‘post_type’][$key]);
}
}
}

return $query;
}

I am using the latest version and if i remove that code then the masonry and blog grid only display if i am logged in as admin.

Any help would be appreciated
