@dvsDave, yes. The pop-ups are text. Thanks for your idea
@Ozidoggy, right! that's a bug. It can be fixed by editing system/application/models/token.php. You need to replace update_count() function with this code:
PHP Code:
function update_count()
{
$this->_add_life();
$this->db->set('use_count', 'use_count+1', false);
$this->db->where('value', $this->token);
return $this->db->update('tokens');
}
