PrestaShop 9.1.x is an important update for merchants who want to keep their online stores modern, stable and ready for future improvements. This version continues to improve the PrestaShop platform with updates related to performance, security, store management, front office experience and technical compatibility.
PrestaShop 9.1.x includes important technical updates such as Symfony 6.4 LTS support, PHP 8.5 support, improved Admin API, and experimental features like multi-carrier and a new discounts manager. These changes help strengthen the platform and make updated themes even more important for merchants who are preparing to upgrade their stores.
However, when upgrading a PrestaShop store, the platform itself is not the only part that matters. Your theme also plays a very important role.

A PrestaShop theme controls many key areas of your store’s front office, including the homepage, category pages, product pages, cart, checkout, menus, banners, sliders, product block, and mobile layout.
If a theme is not compatible with the new PrestaShop version, it may cause unexpected issues such as broken layouts, buttons not working correctly, product images displaying incorrectly, checkout display errors, or some content blocks not loading as expected.
That is why, before upgrading your store to PrestaShop 9.1.x, it is important to make sure your current theme has also been updated and tested for compatibility.
A compatible PrestaShop theme helps reduce the risk of front office issues after the upgrade and gives merchants a smoother path when moving to the latest PrestaShop version.
