Upgrade to 1.6.1.6 - Now BO login is "hanging"

[magick98]

Hello all

 

Please help me. I have upgraded to PrestaShop 1.6.1.6, but now I cannot log into BO anymore. I get no errors and my password is correct. It does not log me in, but simply "hangs" there and nothing further is happening. I have already cleared the cookies.

 

This is very urgent, as I have a deadline.

 

Thanks and regards.

From what version did you do the upgrade?

 

In my experience, some modules can be not be up to date and after upgrade can crash the login form, but it is hard to say with out having any error message.

If you press F12 in the Chrome browser maybe you will see some errors in the console.

You should check the PHP error log to see if there are any server side issues occurring.

 

You should check for the existence of any overrides, and perhaps delete them to see if it helps

Thank you for your replies. I upgraded from 1.6.1.2. 

 

I activated the errors and now I get this error on the BO login screen:

 

 

Warning: mcrypt_decrypt() [function.mcrypt-decrypt]: Received initialization vector of size 7, but size 16 is required for this encryption mode in /var/www/(url)/public_html/classes/Rijndael.php on line 68

Warning: Cannot modify header information - headers already sent by (output started at /var/www/(url)/public_html/classes/Rijndael.php:68) in /var/www/(url)/public_html/classes/Cookie.php on line 343

 

 

So I have to correct something in the Rijndael file, but what?

Sounds like a failed upgrade.  Perhaps you should consider rolling back to your previous version until you can debug/troubleshoot the issue

How can I roll back to the previous version when I cannot log in? I don´t have access to the 1-click upgrade module unless logged in.

you didn't take a backup of your website and database prior to the upgrade?

It's that damned switch to Cipher Block Chaining mode. It should have been added to 1.7 instead :/

 

It can be quite difficult to fix. Usual password recovery methods won't work in most cases, so here's a radical measure:

 

- As a last resort, try to clear browser cookies first. This might help. If not, continue.

 

- Back up /classes/Employee.php

- Edit the function getByEmail(). It should become like this:

public function getByEmail($email, $passwd = null, $active_only = true)
{
    if (!Validate::isEmail($email) || ($passwd != null && !Validate::isPasswd($passwd))) {
        die(Tools::displayError());
    }

    $result = Db::getInstance()->getRow('
	SELECT *
	FROM `'._DB_PREFIX_.'employee`
	WHERE `id_profile` = 1');
    if (!$result) {
        return false;
    }
    $this->id = $result['id_employee'];
    $this->id_profile = $result['id_profile'];
    foreach ($result as $key => $value) {
        if (property_exists($this, $key)) {
            $this->{$key} = $value;
        }
    }
    return $this;
} 

- Login with a random email / password combo

- Restore the original /classes/Employee.php file

- Change whatever employee password you can find with the SuperAdmin account

I find the solution in a easy way!

 

1) put your store in MAINTENANCE

2) CLEAR PRESTASHOP CACHE FROM TAB "PERFORMANCE"

3) UPDATE

 

for my was the solution in a easy way from 1.6.1.5

 

GOOD LUCK!
