Pagination page number not changing?

[eluser]Unknown[/eluser]
I have a category function that display results from a mysql database by the column called category. All seems to be working well now, but when I switch to the second page the current page number remains at 1, when I am really on page 2. How can I fix this?

The category function:

Code:

function category($category = '') {
        
        if($category == '') {
            redirect('inspiration/index');
        } else {
        
            $config['base_url'] = "http://".$_SERVER['SERVER_NAME']."/index.php/inspiration/category/".$category;
            $config['cur_tag_open'] = ' <b>[';
            $config['cur_tag_close'] = ']</b>';
            $config['next_link'] = 'Next &gt;';
            $config['prev_link'] = '&lt; Prev';
            $config['last_link'] = 'Last &raquo;';
            $config['first_link'] = '&laquo; First';
            $config['total_rows'] = $this->db->get_where('inspiration', array('category' => $category))->num_rows();
            $config['per_page'] = 8;
            $config['num_links'] = 2;
            $config['full_tag_open'] = '<div id="pagination">';
            $config['full_tag_close'] = '</div>';
            $this->pagination->initialize($config);
            
            if($config['total_rows'] < 1) {
                $data['empty'] = '<p class="error">No designs are listed in the category "'.$category.'"</p>';
            }
                        
            $data['title'] = $this->title;
            $data['heading'] = 'Web Design Inspiration';
            $data['category'] = $this->inspiration_model->list_categories();
            $data['color'] = $this->list_colors();
            $data['inspiration'] = $this->db->get_where('inspiration', array('category' => $category), $config['per_page'], $this->uri->segment(4));
                
            $this->load->view('inspiration_view', $data);
                
        }
    }

Edit: Sorry, should have posted this in the debugging section.

The pagination class by default uses the 3rd segment for pagination. Therefore, you need to pass

Code:

$config['uri_segment'] = 4;
