You must use the "set" method to update an entry

Question

codeigniter 2.2.2 No changes were made to the site code on the site, only work was carried out through the site admin panel to add information to the site. I do not understand why this error appeared, since before that everything worked correctly. This may have happened because a new ssl certificate was installed. Error: You must use the set method to update a record. File name: admin_m.php Line number: 25 This error occurs when you try to edit information on the site through the admin panel.

function getInfo()
    {
        $this->db->select();
        $this->db->from('tbl_info');
        $this->db->where('id', 1);
        $query = $this->db->get();
        
        return $query->result();
    }
    function editInfo($data)
    {  
    
        $this->db->where('id', 1);
        $this->db->update('tbl_info', $data); // the error refers to the given line of code
        return TRUE;
    }
