My project worked properly before route configure .
this is my project url
 http://localhost/online_support/backend/admin/unsolved_tickets
 and it works fine .
after route configure
$route['unsolved'] = 'backend/admin/unsolved_tickets';
http://localhost/online_support/unsolved
my datatable only shown first page ... pagination , search  does not works any more .
need a solution . Thanks in advance .
