[benedmunds]

when you call logout() see what errors() returns

[vipinvid]

No error occurs it back me login

[benedmunds]

You’ll need to troubleshoot this a bit.

Start by commenting out the redirects and view loads. Add var dumps of the logout() call, along with var dumping the output of errors(). If logout() isn’t throwing any errors then the logout call is likely working and there’s a logic issue somewhere.

[vipinvid]

in logout function call $logout = $this->ion_auth->logout(); echo "logout = $logout", exit; /*****/ It display logout=1 but calling login again logged me without authenticating

[benedmunds]

Make sure there is a redirect after logout and before login so CodeIgniter can initialize the session properly. Let me know if that affects your results.

[vipinvid]

function logout($param = '')
{
    $this->data['title']                    = $this->lang->line('logout');

    $this->data['active_class']             = $this->lang->line('logout');

    // log the user out

    $logout = $this->ion_auth->logout();

    // redirect them to the login page
    if ($param == "password_changed") 
        $this->prepare_flashmessage($this->lang->line('password_change_success_login_to_continue') , 0);
    else $this->prepare_flashmessage($this->lang->line('success_logout') , 0);
    redirect('auth/login', 'refresh');
}

[benedmunds]

Interesting, and login() is returning false on login? but only the second time?

No errors on login?

You should add some troubleshooting code in the model login method next.

[vipinvid]

what type of code ??

[benedmunds]

dump/log at various points to determine where and why it's failing. I'd pay particular interested around login attempts logic and CI session logic.

[vipinvid]

on redirecting to other page login function not working

[benedmunds]

@vipinvid any update on this?

[benedmunds]

Closing due to age, will reopen when/if we revisit this.
