1. Prestashop admin panel kicks out the administrator in the middle of updating product settings (yes, no reason at all).
2. Prestashop store owner cannot login, no matter how many times the browser cache is cleared. It keeps showing the login page again & again.

Top 3 reasons for Prestashop admin login problem

Let’s discuss the top 3 reasons for this problem.

1. Maximum duration of inactivity set – “Admin Controller” manages  Backoffice functionalities in Prestashop. The default cookie inactivity period is set to 15 mins in this file.You’ll be kicked out of the admin panel after 15 mins of inactivity.
2. Use of dynamic IP address – When you are in Prestashop admin panel, it secures the session by tagging your login session with your IP address(via authentication cookie). It constantly checks for this IP address. If your IP address changes, it will invalidate the cookie and and ask you to re-login again.
3. Incorrect values for “PS_SHOP_DOMAIN” and “PS_SHOP_DOMAIN_SSL” – Incorrect domain name given for PS_SHOP_DOMAIN and PS_SHOP_DOMAIN_SSL  in the table ps_configuration.

Prestashop admin login problem – How to fix this error?

To fix this, we primarily use 5 different ways, based on the exact issue the store owner is facing.

But before we get into the details, and you make any changes to the store, make sure that you have the backup of your database and website files.

1. Clear browser cache and cookies

To verify this try to access from another browser or turn on ‘incognito mode’.

2. Clear Prestashop cache

The cache files are located in these locations.

Go to these folders and delete all the files in them.

• /tools/smarty/cache
• OR /tools/smarty_v2/cache

• /tools/smarty/compile
• OR  /tools/smarty_v2/compile

3. Correct the domain name saved in database

Give the correct domain name for PS_SHOP_DOMAIN and PS_SHOP_DOMAIN_SSL  in the table ps_configuration.

You should give the domain name only. For eg: your store URL is http://test.com/store/, you should give the values as:

PS_SHOP_DOMAIN = test.com
PS_SHOP_DOMAIN_SSL = test.com
Copy Code

The install directory should be given in the file “/config/setting.inc.php“.

4. Disable IP address check

Remove the user’s IP address check done by Prestashop.

You can disable it in the file “classes/cookie.php” inside the function “isLoggedBack()“.

Here, remove or comment the following condition.

!Configuration::get('PS_COOKIE_CHECKIP'))Copy Code

5. Increase the cookie inactivity period

The inactivity period is set as 15 mins by default.

You can increase this value in the file “classes/controller/AdminController.php“.

Look for the below code in the file:

if (time $ this-> Context> cookie-> last_activity + 900 <())Copy Code

Here the inactivity period is set as 900s(15 mins). You can replace this value in seconds.
