Call to a member function num_rows() on boolean means your query:

$this->CI->db->get($this->sess_table_name);

is fails due to some error and it returns FALSE, which is the the return type of select query in case of failure.

So first of all check what $this->sess_table_name contains in it and after that print RAW QUERY by using:

 $this->db->last_query();

and check what is the issue.

You can insert a var_dump before if statement. $query must be false.

Maybe two reasons:

  1. Your database connection is lost.
  2. Or, $this->sess_table_name is not a valid data table name.
