Three very important vulnerabilities have been detected in Prestashop: two of the SQL injection type, one of critical severity and the other of high severity, and another high severity XSS injection vulnerability, which could allow any user with administrator permissions to write, update or drop SQL databases regardless of their permissions.

You can see the statement here.


The critical severity vulnerability is SQL filtering and could allow a user to write, update, and delete to the database, even without having specific administrator permissions.

Of the high severity vulnerabilities, one affects arbitrary file reading, which makes it possible for a user with SQL manager access to arbitrarily read any file in the operating system with a SELECT function. While the other high severity vulnerability consists of a possible XSS injection, which could facilitate the hijacking of HTML elements without the need for user interaction.


Prestashop has released a patch and recommends updating to versions 8.0.4 and

The only current way to apply the patch is to update the version of Prestashop to the indicated ones.

If you have a Prestashop 1.7.X you must update to

If you have a Prestashop 8.X you must update to 8.0.4

Reading Time: < 1 minuteDo you have an E-Commerce with¬†PrestaShop¬†and want to configure the Facebook pixel quickly and easily?¬†Then don’t miss this useful guide to integrate Facebook on PrestaShop.

The first thing to do is to log into your PrestaShop panel. Next we will have to distinguish two cases:

  • Newly created PrestaShop store
  • Existing PrestaShop store


Newly created PrestaShop store

If you have just created your E-Commerce site with PrestaShop, know that Facebook is already integrated within it. You can then access it, by going through the forms management.

  • Enter the PrestShop backend
  • Select the entry¬†Forms
  • Select¬†Module Manager or Module Manager
  • Select¬†PrestaShop¬†Facebook
  • Click on¬†Configure

Existing PrestaShop store

If you already have a PrestaShop store and the Facebook module is not installed, the process is very similar to before, but with a small difference.

In particular, you will need to:

  • Install PrestaShop Facebook from the Module Catalog tab or in the PrestaShop marketplace
  • Select the entry¬†Forms
  • Select¬†Module Manager or Module Manager
  • Select¬†PrestaShop¬†Facebook
  • Click on¬†Configure

Alternatively you can also do this second procedure:

  • Open¬†PrestaShop Facebook¬†and download the module
  • Access the Module Catalog and download the module in the backend
  • Configure the module in the Module Manager tab
  • Once the PrestaShop Facebook module is open, select “start” to proceed.

Reading Time: 4 minutesThis guide gives you full control over the process. This has been applied by PrestaShop for several major versions and thus can be applied on very old stores.

Download release
The first step is to download the latest version at .

The download can also be done from the command line:

wget -O

Once you have the folders like classes /, modules /, themes / , etc. you can go to the next step.

Simple Data Cleanup

Avoid overwriting production resources (images, conf…) with default data. These folders can be removed from the new version:

  • img /
  • override /

All other files in the new version will overwrite the existing files. Any changes made to the original source code will be lost.

Also, rename the ‚Äúadmin‚ÄĚ folder to match your store’s admin folder name.¬†This will prevent unwanted duplication of the administration content.

Activation of maintenance mode

As it may cause unexpected behavior for you and your customers during the upgrade, we strongly recommend that you turn on maintenance mode during the upgrade.

You can do this in your admin panel:

  • On PrestaShop 1.7, in Store parameters> General> Maintenance tab
  • On PrestaShop 1.6, in Shop parameters> Maintenance

Adding your IP address will allow you to access your store while it is in maintenance mode. This way, you can make sure everything is working properly before allowing your customers to access it again.

Copy the files

In this step, we ‚Äúupdate‚ÄĚ the PrestaShop files by copying the content of the new version to the existing store.

Disable the cache

You may have activated a caching system (e.g. memcache) on your store.¬†If so, be sure to disable it in ‚Äú¬†Advanced Settings‚ÄĚ> ‚ÄúPerformance‚Ä̬†.¬†You can enable it again once the update process is finished.

Note on the ‚ÄúVendor‚ÄĚ folder: the previous updates of PrestaShop 1.7 showed that conflicts can occur when merging the new supplier / folder with the old one.¬†To avoid this problem, it is recommended to delete this folder in the existing store before copying the new one.

On Windows, copy the new contents of the folder and paste it into your store folder.¬†You will receive warnings that the files already exist in the destination folder.¬†Choose “overwrite” to continue.

On Linux, the copy can be done in your terminal:

cp -R <path_to_the_new_release>/* <path_to_the_current_shop>/

For example:

cp -R ~/Downloads/prestashop/* /var/www/html/

Database update

Once the files have been copied, your store database is ready to be updated.

All changes to be applied have been defined in the installation folder, their execution can be performed with a specific PHP script.

When ready, run the install / upgrade / upgrade.php file .

This can be done with a browser, by reaching the address http: // <shop_domain> /install/upgrade/upgrade.php or from the command line of your server:

php install/upgrade/upgrade.php

In both cases an XML log will be displayed. The result can be found in the result of the attribute of the first <action> tag:

  • ok¬†if updates have been found and performed
  • error¬†if something went wrong
  • info¬†for subsequent actions, viewing process details

Execution log

When the update script has detected some updates to apply, the executed SQL queries will be listed along with their result.

<?xml version="1.0" encoding="UTF-8"?><action result="ok" id="">
<action result="info" id=""><![CDATA[[OK] PHP : /* PHP:ps_update_tabs(); */]]></action>
<action result="info" id=""><![CDATA[[OK] SQL : ALTER TABLE `ps_currency` MODIFY `name` varchar(64) NOT NULL]]></action>
<action result="info" id=""><![CDATA[[OK] SQL : SET SESSION sql_mode = '']]></action>
<action result="info" id=""><![CDATA[[OK] SQL : SET NAMES 'utf8']]></action>

You can double check that each action is marked “OK”.¬†If not, further details will be shown after the request, which can help you resolve the issue and re-run the request manually on your database.¬†In some cases, you may need to restore the database backup and start over.

Error codes

You can also see an error code. Each code is related to a message described here:

  • Error n.¬†27: The store is running a newer version than the content provided by the installation folder.
  • Error n.¬†28: The store is already at the version you are trying to upgrade to.
  • Error # 29: The current version could not be found.¬†Check the database parameter file and database connection.
  • Error n.¬†31: unable to find upgrade directory in installation path, install / upgrade / sql folder exists and is not empty?
  • Error # 32: No updates need to be applied.
  • Error # 33: Error loading an SQL update file.¬†Check the permissions of the install / upgrade / sql folder.
  • Error # 40: The version provided in the install / install_version.php file is not valid.
  • Error # 43: Error updating database schema using doctrine.
  • Error # 44: Error updating translations.
  • Error # 45: error while enabling the theme.


Before we go any further, we will have to do some cleaning.

The installation folder, used to perform database updates, is no longer needed and can be safely deleted.
When you open your store (in the front or back office) on your browser, you may experience some visual problems. This may be because your old resources are still served by a cache. Reload them by forcibly refreshing the page (press ctrl + R on Windows / Linux or cmd + R on Mac OS) or by clearing your browser cache.

Update the modules

Your module files were updated while the file was copied, however many of them may require additional database changes. Check the module page in your Back Office to see if updates are pending.

Go to your admin panel and log in. You will notice that the version displayed has changed on the login page. Then in the menu, click on the form page to reach your catalog.

On PrestaShop 1.6, this page is located in ‚ÄúModule and services‚ÄĚ.¬†Click “Update All” at the top of the page to perform all available updates:


On PrestaShop 1.7, the same functionality can be found on the Enhance >> Modules page, in the “Notifications” tab:


1-click update module

If the manual process seems too tedious, there are other solutions to complete an update.

PrestaShop provides free 1-click upgrade module on the marketplace and admin panel of your store. It automatically carries out the previously mentioned process and is available for almost all versions of PrestaShop.

You can read more about it here.



Reading Time: 3 minutesPrestashop¬†has quite strict security features and one of these is certainly the duration of the session timeout, which is rather short.¬†This ploy is to reduce your application’s exposure to session-based attacks, such as session cookie theft.

However, this can be quite annoying for anyone who is working with the platform. Store admins may be logged out of the admin interface if they are idle for some time. This can be very frustrating.

Today then I’ll show you why it happens and how to fix this error.


Prestashop Admin Login Problem – Where do you see this error?

This problem usually occurs when one of these conditions occurs:

  • Prestashop admin panel logs out the admin while updating the product settings.
  • The Prestashop store owner cannot log in, no matter how many times the browser cache is cleared.
  • Prestashop admin panel disconnects the owner after a few minutes of inactivity.

Prestashop admin login problem: 3 reasons

Let’s see what are the 3 main reasons why the Prestashop admin login problem occurs.

  • Maximum duration of inactivity set – ‚ÄúAdmin Controller‚ÄĚ manages the back office functions in Prestashop.¬†The default cookie inactivity period is set to 15 minutes in this file.¬†You will be removed from the admin panel after 15 minutes of inactivity.
  • Use of the dynamic IP address: when you are in the Prestashop administration panel, this system protects the session by tagging your login session with your IP address (via authentication cookie).¬†Constantly check this IP address.¬†If your IP address changes, it will invalidate the cookie and ask you to log in again.
  • Incorrect Values ‚Äč‚Äčfor ‚ÄúPS_SHOP_DOMAIN‚ÄĚ and ‚ÄúPS_SHOP_DOMAIN_SSL‚ÄĚ – Wrong domain name provided for PS_SHOP_DOMAIN and PS_SHOP_DOMAIN_SSL in the ps_configuration table.

Prestashop admin login problem: how to fix this error?

To solve this problem, we mainly use 5 different ways, based on the exact problem the store owner is facing.

But before you get into the details and make any changes to the store, make sure you have the database and website files backed up.

1. Clear your browser cache and cookies

To check this, try to log in from another browser or activate the “Incognito mode”.

2. Clear the 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 / compil

3. Correct the domain name saved in the database

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

You should only provide the domain name.¬†For example: your shop URL is, you should provide values ‚Äč‚Äčlike:


The installation directory should be indicated in the “ /config/ “ file.

4. Disable IP address checking

Remove the check of the user’s IP address performed by Prestashop.

You can disable it in the ‚Äú¬†classes / cookie.php¬†‚ÄĚ file inside the ‚Äú¬†isLoggedBack ()¬†‚Äú function.

Here, remove or comment on the following condition.

! Configuration :: get (‘PS_COOKIE_CHECKIP’))

5. Increase the period of inactivity of cookies

The inactivity period is set to 15 minutes by default.

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

Look for the following code in the file:

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

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