PrestaShop, a popular tool for managing e-commerce websites, regularly undergoes updates to provide new features and fix bugs. These updates are crucial for ensuring the security and efficiency of e-shops. However, many PrestaShop users face the problem that after updating the system, their own modifications in both the core and modules are erased.

Why Customizations Are Lost

When developers or e-shop owners make modifications directly in the PrestaShop core or its modules, these changes are not part of the official codebase. During a PrestaShop update, the system downloads and replaces core and module files with new versions, overwriting custom modifications. This process is unavoidable because the system cannot recognize which changes were made by the user and which are part of the official update.

Preventing Loss of Modifications

The best solution to prevent the loss of customizations is to avoid direct changes in the core or modules. Instead, developers should utilize code overrides or create custom modules to implement the desired functionalities. This way, modifications remain separate from the PrestaShop core and are not affected during updates.

Guides and Resources for Proper Customization Handling

There are numerous guides and community forums available to help developers properly implement changes without risking their loss during updates. It is strongly recommended for developers to familiarize themselves with the official PrestaShop documentation, which contains information on best practices for extending the system's functionality.

PrestaShop updates are necessary to maintain the security and functionality of e-shops. However, careless modifications in the core or modules can lead to their loss during the update process. By adopting the right approach and adhering to established practices, developers can protect their modifications while taking advantage of the latest features and fixes that PrestaShop offers.
