Is your PrestaShop store experiencing issues? Our experts step in quickly to diagnose and fix all types of bugs.
Since 2017, we have been helping e-commerce merchants resolve their PrestaShop technical problems. Free diagnosis, transparent pricing and guaranteed fixes.
Explore the most frequent problems encountered on PrestaShop stores and how we resolve them efficiently.
A 500 error on PrestaShop is often caused by a misconfigured .htaccess file, an incompatible module or an unsuitable PHP version. Our experts analyse your server logs and pinpoint the exact cause within minutes. We restore your online store quickly to minimise the impact on your sales.
Module conflicts are one of the most common causes of PrestaShop malfunctions. A module may clash with another or with the PrestaShop core after an update. We identify the offending module, resolve the conflict and verify the compatibility of your entire configuration.
Migrating from PrestaShop 1.6 to 1.7 or from 1.7 to 8.x is a delicate operation that requires deep expertise. We handle the complete migration of your product catalogue, customers, orders and configurations. Data integrity is our top priority throughout the entire process.
A faulty payment module on PrestaShop means lost sales. Whether it is Stripe, PayPal, Mollie or another provider, we diagnose transaction errors, callback failures and stuck orders. We restore your checkout flow so your customers can complete their purchases without interruption.
A slow PrestaShop store drives visitors away and hurts your search engine rankings. We optimise SQL queries, properly configure Smarty and CCC caching, and reduce page load times. The goal: a fast site that delivers a smooth shopping experience for your customers.
PrestaShop stores are regularly targeted by attacks: SQL injections, XSS vulnerabilities, credit card skimmers and unauthorised back-office access. We perform a thorough security audit, clean infected files and implement lasting protections to prevent future intrusions.
A poorly integrated PrestaShop theme can cause display problems, responsive breakdowns or JavaScript bugs. We fix CSS anomalies, resolve module conflicts and ensure flawless rendering across all devices, from mobile to desktop.
Poor search rankings on PrestaShop are often linked to non-rewritten URLs, a missing or misconfigured sitemap, duplicate meta tags or missing structured data. We audit your SEO configuration, fix technical issues and implement best practices to improve your visibility on Google.
A simple and transparent three-step process to resolve your PrestaShop issues quickly.
Use our smart chat or contact form to describe the issue you are experiencing on your PrestaShop store. Our AI assistant gathers the essential information to speed up the diagnosis. No technical knowledge required, simply explain what is not working.
Our PrestaShop experts analyse your problem in depth. We examine logs, server configuration, installed modules and source code to identify the exact root cause. You receive a clear diagnosis and a transparent quote.
Once the quote is approved, we work directly on your PrestaShop store. The fix is applied, tested and documented. You validate that everything works correctly before closing the ticket. Your satisfaction is our guarantee.
Since 2017, our team has built deep knowledge of the PrestaShop ecosystem. We master the CMS architecture, its override mechanisms, its hook system and its database structure. This expertise allows us to work efficiently on every aspect of your online store.
We work with every PrestaShop version ever released, from 1.4.x through to the latest 9.x, including 1.5, 1.6, 1.7 and 8.x. Whether your store runs on a legacy version or the latest Symfony-based generation, we have the expertise to step in.
We fix broken modules, modify existing modules to fit your needs, and build custom modules from scratch. We also handle the migration of your legacy modules to the Symfony architecture introduced in PrestaShop 8 and 9. Payment gateways (Stripe, PayPal, Mollie), shipping providers (DHL, UPS, FedEx), SEO modules: whatever the module, we can help.
PrestaShop runs on various environments that we master: Apache and Nginx, PHP 7.2 through 8.3, MySQL and MariaDB. We optimise your server configuration to get the best performance from your hosting, whether shared, VPS or dedicated.
