I had some problem with DX_Auth lib last night. I don;t know why but in my localhost wamp everything works but in my hosting not works and I must to disable some commands and function, I think it has some problem with PHP4, also after some searches it shows everytime error in this command line:
```
$query->num_rows()
```
the last error was in thin function:
```
function is_max_login_attempts_exceeded()
    {
        $this->ci->load->model('dx_auth/login_attempts', 'login_attempts');
        return $this->ci->login_attempts->check_attempts($this->ci->input->ip_address()->num_rows()>= $this->ci->config->item('DX_max_login_attempts'));
    }
```
and as you see there we have that num_rows again.
it would be highly appreciate d if you help me in this matter

best regards

I changed these line 803 in DX_Auth Lib:
```
return ($this->ci->login_attempts->check_attempts($this->ci->input->ip_address())->num_rows() >= $this->ci->config->item('DX_max_login_attempts'));
```
to this:
```
$query = $this->ci->login_attempts->check_attempts($this->ci->input->ip_address());
        return $query->num_rows() >= $this->ci->config->item('DX_max_login_attempts');
```
and these line 1092 of the lib:
```
$user_id = $query->row()->id;
```
to this:
```
$query = $query->row();
            $user_id = $query->id;
```
now the script can be loaded but when trying to login it gives again the following error:

Fatal error: Call to a member function on a non-object in /hsphere/local/home/.../system/application/libraries/DX_Auth.php on line 802

please guys I can’t understand it please help pro’s

Could you debug query? It seems query is not an object for some reason. DB issue or smthing else?
I’m a noob like you, trying to help.

My last error:

return $query->num_rows() >= $this->ci->config->item('DX_max_login_attempts');

that I changed it to:

return $query->num_rows >= $this->ci->config->item('DX_max_login_attempts');

but still I have errors like before

add this lib to your lib direcory. load it then do this : vd::dump($yourVar); and see the magic.

lib :

<?php
/**
 * VAR DUMP plus
 */
class vd {
    function dump ($var, $name = '') {
        $style = "background-color: whitesmoke; padding: 8px 8px 8px 8px; border: 1px solid black; text-align: left;";
        echo "<pre>" .
            ($name != '' ? "$name : " : '') .
            vd::_get_info_var ($var, $name) .
            "</pre><p>“;<br />

it’s a standalone file. You just need to load it and execute vd:dump($youVarHere); like I previously said.

Ive been wrapping my head around this library and for the most part I like it. One thing I would suggest is that when someone tries to login with an incorrect username, that you don’t report that to the user - “Username not exist.”. The same goes for the password being wrong with the correct username supplied - “Your password was incorrect.”. This just makes it easier for hackers by letting them know where to focus their efforts. A better message is “Your username or password are incorrect” or something similar, for both cases. I know you are using captcha as a backup, but this is getting easier to defeat with advancements in on-screen OCR.

Just my .02
