Updating the PrestaShop e-commerce system is essential to ensure the security, performance, and functionality of your online store. Older software versions may contain bugs, security vulnerabilities, or incompatibilities with new modules and templates. In this article, we’ll guide you through the step-by-step process of updating PrestaShop so that your e-commerce store continues to operate smoothly.

Why It’s Important to Update PrestaShop

Updating PrestaShop not only improves the security of your store but also brings new features, bug fixes, and performance enhancements. An outdated version of PrestaShop can be vulnerable to hackers or cause incompatibility issues with certain modules or plugins.

1. Preparing for the PrestaShop Update

Before you proceed with the actual update, it's important to follow a few preparatory steps to ensure a smooth process and avoid any potential issues.

Backup your database and files: The first and most crucial step before any update is creating a backup of your database and all files. This can be done manually via an FTP client (such as FileZilla) or through backup modules available within PrestaShop.

Check module and theme compatibility: Before starting the update, check whether all your modules and themes are compatible with the new version of PrestaShop. Some modules and themes might not function correctly after the update if they are not optimized for the new version.

2. Step-by-step Guide to Updating PrestaShop

You can update PrestaShop in several ways, but the most commonly used method is the 1-Click Upgrade module, which is officially supported by PrestaShop.

Using the 1-Click Upgrade module:

1. Install the 1-Click Upgrade module: If you haven’t installed it yet, go to the PrestaShop back office -> Modules -> Module Catalog and search for "1-Click Upgrade." Download and install the module.

2. Configure the module: After installation, go to the module’s settings and select the PrestaShop version you want to upgrade to. It is always recommended to upgrade to the latest stable version. In the settings, you can choose whether to update core files only or include translations, themes, etc.

3. Backup via the module: The 1-Click Upgrade module also offers an automatic backup option for files and the database before the update. However, it’s still a good idea to have a manual backup as an extra precaution.

4. Start the update: After configuring the module, click the "Upgrade" button. The update process may take a few minutes depending on the size of your e-commerce store and server environment. Once the update is complete, you will receive a notification about its success or any issues that occurred.

3. Manually Updating PrestaShop

If, for any reason, you prefer not to use the 1-Click Upgrade module, the update can also be done manually.

Download the latest version of PrestaShop: Go to the official PrestaShop website and download the latest version. Then, connect your FTP client to your server and upload the new files to overwrite the old versions.

Database update: After uploading the files, you need to update the database. You can use the install script found in the PrestaShop directory. Go to your store’s URL and append /install to it, then follow the instructions to update the database.

Post-Update Testing and Verification

After completing the update, it's crucial to perform several checks to ensure everything works correctly:

• Test store functionality: Go through key functions like the checkout process, customer registration, payments, and shipping. Make sure everything works as expected.
• Check modules and themes: Ensure that all the modules and themes you use function properly after the update. If a module does not work correctly, try updating it or contact its developer.
• Monitor performance and loading speed: After the update, observe if there are any changes in page loading times or overall store performance. Some updates might slow down the site if modules or themes are not fully compatible.

Potential Issues When Updating PrestaShop and How to Fix Them

1. White Screen (White Screen of Death): If you encounter a white screen after the update, it may indicate a problem with an incompatible module or theme. In this case, enable debug mode to identify where the issue lies.

2. Module issues: If a module stops working, check if there’s an updated version compatible with the new PrestaShop version. If not, you may need to find an alternative.

3. Database errors: In case of database issues, it might be due to an unsuccessful update of certain tables. It’s a good idea to check your backups and manually fix the problem or consult PrestaShop developers for assistance.

 

Updating PrestaShop is critical for the long-term stability and security of your online store. Whether you use the automatic 1-Click Upgrade module or choose to manually update, always ensure proper preparation and backups. Regular updates not only keep your store running smoothly but also bring new features and improvements that can benefit your business.

The process of updating PrestaShop may seem challenging, but with careful preparation, most problems can be avoided.
