When performing an upgrade to the store, it is highly advisable to perform make the back backup only after the store has been put in maintenance mode. This way, you are certain that no customer data is lost if you have to revert the upgrade to that backup. Do not perform the upgrade before both files and data have been properly backed up on your computer.


The processes described in this chapter will have you transfer files using an FTP client, download SQL data from a web server using online tools, and even delete all your online files and data. Do not attempt this if you do not have a good grasp of these tools and technologies. If you must (for instance, if your store is broken after a failed upgrade), get assistance from a technical friend, and take the time to perform each step completely. If not, you might lose your store forever.

Making your own backup

First, create a folder on your computer, where you will store both your PrestaShop files and data. Put the current date in the folder's name, in order to know exactly from when that backup is.


This process may take some time, depending on your server's speed. PrestaShop 1.5 has roughly 7 500 files in 970 folders, and that's not counting your own files (product images, themes, modules, etc.), or your visitors visitor's custom images. Let the process go to completion, ; do not touch your FTP client until it is done.


  1. Log into phpMyAdmin on your web server.
  2. From the main login screen, select "Databases".
  3. Click the name of PrestaShop's database to open it.
  4. In the database screen, click the "Export" tab on the top set of tabs.
  5. In the export screen:
    1. Make sure all of PrestaShop's tables are selected, and only these. They should start with the ps_ prefix (or any prefix you have chosen to use when installing PrestaShop).
    2. Make sure the "SQL" radio button is selected.
    3. In the "Structure" section, tick the following boxes:
      • "Structure".
      • "Add IF NOT EXISTS".
      • "Add AUTO_INCREMENT".
      • "Enclose table and field names with backquotes".
    4. In the "Data" section, tick at least the following box:
      • "Data".
    5. In the "Save as file" section:
      • Tick "Save as file".
      • Leave the template alone (usually, "__DB__").
      • Tick the "zipped" or "gzipped" box, in order to compress the file before downloading it.
    6. Click the "Go" button.
  6. The browser should start downloading the data file. Save that file in your computer's backup folder.


Restoring your backup

After an automatic upgrade failed (which is the only reason why you should revert said upgrade), if you can still access PrestaShop's administration page and use the 1-Click Upgrade module, use that module's "Revert" tool in order to start the process of restoring both the files and data that it backed up when you started the automatic upgrade. Read the "Automatic update" of this guide for more information on that process.
If you cannot access the administration or the module, or if you simply did not use the 1-Click Upgrade module to upgrade to the latest version of PrestaShop, then follow the instructions in this section.

One issue with the 1-click Upgrade module is that you have to have to be connected to the PrestaShop administration if you want to start rolling back to the previous version – and in some unknown unpredictable configurations, the upgrade can prevent you from logging back again, or even render the administration unusable (note: empty the browser's cache and reload the administration several times before you deem it unusable... It might simply be a temporary CSS issue).


This local copy of your site should be extremely recent: at best, it should have been made right after you put PrestaShop in maintenance, and before you started any upgrade script (either automatically or manually). This way, you ensure that you can get back to the most recent version of your shop, and not lose any date data (users, sales, stats, etc.).


Now, you have a complete and recent local copy of your shop in its previous version, and your attempt at bringing your online site the latest version of PrestaShop has failed, resulting in a useless administration (the front-end should be inaccessible, since your shop should be in maintenance mode). Going back to the previous version means restoring your local copy on your online server, and that implies starting from a clean slate in order prevent old and new data to mix and further break your site.


Do not worry: since all these files and data have been copied are already safe and sound on your servercomputer, you will be able to restore them quickly. But since visitors will keep coming to your shop, you have to display a custom maintenance page while you are working to restore your shop.


Indeed, the existing maintenance page relies heavily on PrestaShop to display some information: shop name, shop logo, translation, CSS file, meta data, etc. Even if your shop is currently in maintenance mode, and is therefore displaying the maintenance page to visitors, that page will not work anymore as soon as you delete your datedata... and it won't even be here as soon as you delete your files, as that page is from the current theme, under the maintenance.tpl name.


Here is a basic example:

Code Block
titleSample maintenance .htmlpage
<!DOCTYPE htmlhtml>
PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
<html xmlns="" xml:lang="{$lang_iso}" lang="{$lang_iso}">
    <title>Our shop is under maintenance</title>    
    <p>In order to perform site maintenance, our online shop has shut down temporarily.</p>
    <p>We apologize for the inconvenience and ask that you please try again later.</p>

Copy this code into a maintenanceindex.html text file, and upload it in PrestaShop's folder using your FTP client. On most servers, the index.html file takes precedence over the index.php file, so as you soon as you upload index.html to PrestaShop's root folder, your shop should display this maintenance page instead of PrestaShop's one. Check your server's settings to make sure it is so.

Deleting files

Connect to your hosting space using your FTP client. Go to PrestaShop's folder (if it is not located at the root), select all the files and folders in PrestaShop's folder (except maintenanceindex.html, your custom maintenance page), and delete them all. Obviously, you should only do this if you are certain that you have an exact copy of your files backed up on your computer.

This can take a couple minute, as PrestaShop has more than 7 000 files. While they are being deleted, go delete the data tables (next section).

Deleting data

Open your database's manager – usually, your host will provide you with phpMyAdmin or any custom tool. Reach the database for your installation of PrestaShop. Select all the tables which start with ps_ (or the table prefix you chose when installing PrestaShop); if PrestaShop is the only tool using this database, you can simply click the "Check All" link at the bottom of the tables in order to select all tables quickly.

Then, open the "With selected:" drop down menu at the bottom of the tables, and select "Drop". On the next screen, phpMyAdmin will ask you for a confirmation: click the "Yes" button. Again, you should only do this if you are certain that you have an exact copy of your data tables backed up on your computer.

Let the process happen. Finally, phpMyAdmin will display the database, devoid of any table.

Your server is now empty of any PrestaShop file and data, except for the index.html maintenance file. It is now time to fill it put your store back up again, this time with replacement file and data that you know do work!

Restoring you files and data

As soon as your FTP client is done deleting online files, start uploading the ones that were stored on your computer! As this process can take some time, it is important to not lose some precious minutes (and therefore potential sales) being keep by keeping your shop offline for more time than necessary.

Restoring your files

This process is as easy is as the one that you followed when backing up your files:


PrestaShop's online folder should be empty, so as to make sure new and old files do not conflict. If you didn't delete all online files (after you backed them up, of course), you must tell your FTP client to overwrite any existing file. You must not keep any trace of the files from the upgrade that failed.

Restoring your data

This The process described here uses phpMyAdmin, which is a standard web tool. If you web host makes you use another tool for managing your databases, you will have to adapt this process to that tool. Check your webhost's documentation on the matter.


  1. Log into phpMyAdmin on your web server.
  2. From the main login screen, select "Databases".
  3. Click the name of PrestaShop's database to open.
  4. In the database screen, click the "Import" tab on the top set of tabs.
  5. In the import screen:
    1. In the "File to import" section, click the "Browse..." button and find your backup file from your data. It can be either the raw SQL text file (.sql), or a compressed version of it (, .sql.gzip, .sql.tar.gz, etc.).
    2. In the "Format" section, make sure the "SQL" format is selected.
    3. Click the "Go" button.
  6. The browser should start uploading the backup file.

If you have more than one backup data file, import them one after the other.

Finally, remove your maintenance page (named index.html). There you go: your shop is back online!
