" sub-tab.

The configuration screen presents you with a series of sections, providing information, tools and settings.


This section compares your version of PrestaShop with the latest stable one. You can quickly see whether you need to update or not. If you know that there is a newer version available than the one presented, you can trigger a version check by clicking the "Check if new version available" button.

If you want to check for a version other than a stable one (for instance, beta, RC , etc.or any other unstable version), click on the "More options (experts Expert mode)" button. This will open a new section, named "Advanced mode", where you can choose the distribution channel to which you want to update.

This section enables you to pinpoint exactly which version you want to upgrade your current PrestaShop installation to.

  • Channel. The default Choose the distribution channel that you want to use. The recommended selection is "Minor releases", which means "any stable release above the current one". The other options are:
    • Major releases: only . Only major stable releases above your own: 1.3, 1.4, 1.5, etc.
    • Release candidates: . RC versions are deemed stable enough to be tested by the majority, but not stable enough to be the real release. Use at your own risks.
    • Beta releases, alpha releases: these . These are development versionversions. Use at your own risks.
    • Private release: sometimes. Sometimes, the PrestaShop developers uploads upload a private test version. If you have the right URL and MD5 hash key, you can update to this version easily using this channel. If you check the "Allow major upgrade" box, you indicate that are only interested in major releases.
    • Local archive: . To be used if you have downloaded the version you want to upload to in the correct local folder, /admin/autoupgrade/download.
    • Local directory: . To be used if you have downloaded the version you want to upload to in a custom the /admin/autoupgrade/latest/prestashop folder.

  • url. The URL to the latest version in the chosen channel.
  • md5. The hash check for the latest version in the chosen channel.


The "Current configurationChecks" section gives you useful information on your current PrestaShop installinstallation, and how it might interact with the automatic upgrade:


. You must make sure that all the checks are validated before you can launch the upgrade.

  • Module version up-to-date (0.6.1-dev). Indicates whether you need to update the update module itself. If you have just installed it, there is little chance you will need to update it.
    Root directory status: indicates If you do not have the latest version of the module, a button appears below this field, marked "Install the latest by clicking 'Add from my computer'". Clicking it takes you to the "Modules" page. From there, click on the "Add a module from my computer" link to reveal the pre-filled form. Click the "Download this module" button to start updating the module. Finally, go back to the 1-Click Upgrade configuration page to continue performing pre-upgrade checks.
  • Root directory is fully writable. Indicates if the read/write permissions are correctly set. If not, you will have to change them, using your FTP client, such as Filezilla.
    See the Getting Started guide for a quick explanation of how to perform a CHMOD.
  • Autoupgrade allowed: indicates whether your install can be upgrade using this tool or not.
  • Shop status: indicates Shop deactivated. Indicates if your shop is active or in maintenance mode. You must put your shop in maintenance mode during the whole process (file backup, database backup, automatic upgrade, verification), so as to prevent customers from losing orders... and you from losing clients. The module will not do it for you. disable your shop for you, but does provide a button leading to the shop preference page:
    • PrestaShop 1.4: enable/disable the shop in the main "Preferences" tab.
    • PrestaShop 1.5: enable/disable the shop in the "Maintenance" page, under the "Preferences" menu.
  • Cache deactivated: indicates if . Indicates whether your shop's cache is enabled or disabled. You must disable it during the whole process. The module will not do it for you.
    • PrestaShop 1.4: enable/disable the cache in the "Performances" page, under the "Preferences" tab.
    • PrestaShop 1.5: enable/disable the shop cache in the "> Performance " page, under the "Advanced parameters" menu.
  • PHP time limit : the disabled. The automatic upgrade can be a lengthy process, as it needs to download the archive from, unzip it on the server, replace the currently installed files, then trigger the update itself. Hence, the PHP settings might be too low, and break the upgrade altogether, mid-process at worse. In this rowfield, PrestaShop gives you an indication of the current PHP settings. Ideally, it should indicate "disabled".
  • Options chosen. Before launching the upgrade, you must make sure that you understand the settings. The "Backup options" and "Upgrade options" sections are available at the bottom of the page, and if the settings have not yet been saved, a button takes you to them.

All these indicators must be green for the upgrade to work. Otherwise, the upgrade button will not appear.


  • Backup my files and database (required). It is not even an option: you must have your files backupedbacked-up, and the module will take care of this for you.
  • Back up my images. You should let the module take care of your images too, in order to be able to do a clean re-install again by re-uploading your files.


  • Preserve the original theme. The upgrade process overwrites the default theme with its latest incarnation. If you have made changes to the theme directly, you can protect these changes by choosing "Yes". As a reminder, it is NOT recommended to edit the default theme! You should make a copy of the theme, and make changes to that copy.
  • Keep default mails. An update might bring new default e-mail templates. By default, the upgrade will replace the existing ones with the ones from the newer archive, and add the new templates. If you have customized your templates, it is recommended you keep them. You would then have to customize the new templates in order to fit the general style of your shop.
  • Deactivate custom modules. It is recommended to choose "Yes" for this option, as some module might prove a hindrance when upgrading PrestaShop.

The Upgrade process

Once all the indicators are green, the update button appears in the "Upgrade" section.

Wiki Markup
The area below the "Upgrade" section will then scroll with a list of the various changes brought to your PrestaShop install: removed files (normally, the ones for the default theme), location of the backup archive (normally in the {{/\[admin\]/autoupgrade}} folder), files added to said archive, files copied from the new version (and therefore marked as upgraded), etc. A lot of files are thus mentioned, and you do not need to read it all\!


The rollback's status is indicated at the same location as the one for the upgrade process'.
