Prestashop cant login in admin

Question

Several days ago I couldn't access the admin panel on my site based on prestashop platform. After entering login and password, I was redirected to login page again and everything repeated.

The site is hosted on a dedicated server, where some other prestashop sites I am developing are hosted too. After trying to access the admin panel on these sites I get the same "error".

What do you think, what is problem?

Prestashop ver.: 1.4.7.3 and 1.4.8.2

Server: CentOs, PHP

Answer 1

This is what worked for me: in the adminstration>preferences control panel, set "Check the Cookies IP address" to "No."

Answer 2

In case you've moved prestashop from a local version or from another domain, in addition of the classic.

update ps_configuration table set value="www.myshop.com" where name ="PS_SHOP_DOMAIN";

update ps_configuration table set value="www.myshop.com" where name ="PS_SHOP_DOMAIN_SSL";

Check the table called ps_shop_url, and update domain and domain_ssl field, and physical_url as well.

Example:

update ps_shop_url set domain='www.myshop.com', domain_ssl='www.myshop.com', physical_url='/';

Answer 3

I had the same issue after adding a NGINX as reverse proxy in front of my Apache web server.

The problem was from the « Check the IP address on the cookie » parameter set to « yes ». Since i was locked out from admin and could not change it, i did it directly in the database with this SQL request :

UPDATE ps_configuration SET value = 0 WHERE name='PS_COOKIE_CHECKIP';

PS : ps_ is my table prefix, you may adapt it to your settings.

There are some possible things that could have happened to prevent your old passwords from working. One could be that your _COOKIE_KEY_ changed.

You can try to use the following script to generate a new password hash. You can then replace it in the database in the xxxx_employee table (where xxxx_ is your table prefix). I hope that works for you. In any case: keep a backup of your old hashes.

Here is the small script:

<?php
require(dirname(__FILE__).'/config/config.inc.php');
echo Tools::encrypt($_REQUEST["pw"]);

Don't forget to remove the script from your server once your done!

Answer 5

I know this is old but it may help someone, turn errors on by opening /config/config.inc.php.

Look for the line:

ini_set('display_errors', 'off');

change it to:

ini_set('display_errors', 'on');

EDIT: changed a seemingly typo

Here is some things you can try :

1/ Clear your browser cache and your cookies

2/ Try using Firefox instead of Chrome (which seems have some unexpected problems)

3/ Check PS_SHOP_DOMAIN and PS_SHOP_DOMAIN_SSL in ps_configuration table

4/ Manually clear smarty cache : remove all files from tools/smarty/compile and tools/smarty/cache

5/ Disable the IP check in classes/Cookie.php (this can causes many issues with dynamics IP) : in isLoggedBack(), remove or comment the fourth condition :

AND (!isset($this->_content['remote_addr']) OR $this->_content['remote_addr'] == ip2long(Tools::getRemoteAddr()) OR !Configuration::get('PS_COOKIE_CHECKIP'))

6/ Make the expire time shorter for cookies (IE can have issues with longest time cookies) : in classes/Cookie.php constructor,

set : $this->_expire = isset($expire) ? (int)($expire) : (time() + 3600);

instead of $this->_expire = isset($expire) ? (int)($expire) : (time() + 1728000);
