You should post some code so that someone can see the problem and help you.

Edit: wow. I look like an idiot asking for some code.

Remove the quotes from the number in $config[‘per_page’]=‘5’; By adding quotes you're passing it as a string, where the Pagination script is expecting a numeric integer. That's what the error is saying, basically - "Hey, this isn't a normal integer!"

I just realized that your model is returning an array of DB query results for your $config['total_rows']. That's definitely not what you want there. You'll want to count those rows, not return them.

BTW I want to clarify something - quotes are okay when defining numbers for the total_rows and per_page variables in the pagination library. I was wrong about that. The ceil() and other numeric functions will assume the number is a float type, and work normally. The problem is with your model returning an array, not a number.

thank you!.it work...
edit model:

function search_count($s){
$this->db->select('id,title,content,created,region');
$this->db->like('title',db_clean($s));
$this->db->orlike('content',db_clean($s));
$this->db->orderby('title','asc');
$this->db->where('status','active');
//$this->db->get('classifieds');
return $this->db->count_all_results('classifieds');
}

thank again!
