We fix the issues costing you sales
The most common PrestaShop issues—the ones that can stop your revenue in seconds. We’ve fixed each of them dozens of times.
500 error & blank page
Website completely inaccessible, blank screen, or fatal PHP error after an update or module installation. We identify the cause and get your store back online.
Payment & order processing issues
The checkout crashes, orders can no longer be completed, and Stripe or PayPal payments fail. This is the costliest type of outage, so we treat it as our absolute priority.
Back office inaccessible
Unable to log in, stuck in a login loop or dealing with broken permissions? We restore access without losing your data.
Theme or module crashing
Broken layouts, module conflicts, faulty overrides. We fix them properly without disrupting the rest of your store.
Hacking & code injection
Malicious redirects, infected files, or a store blacklisted by Google. We clean up, secure, and harden your website.
Slow site & failed migration
Slow pages, a failed upgrade, or an overloaded database. We stabilise your store, then optimise it for lasting performance.
An emergency isn’t a marketing angle—it’s simple arithmetic
A store outage keeps costing you money: wasted paid traffic, abandoned carts, lower search rankings, and customers switching to competitors.
Beyond urgent fixes: your day-to-day e-commerce agency
We do more than troubleshoot. We build, improve, and manage online stores—including our own.
We also work extensively with Shopify — especially when it’s time to seriously consider whether to stay on PrestaShop or migrate.
Who works on your store
Presta Debug is an agency of developers based in France with over 15 years of experience in e-commerce and PrestaShop. No freelance marketplace, no outsourcing overseas: the same people diagnose the issue, fix it and explain what happened.
What sets us apart: we run our own online stores. When your checkout goes down, we know exactly what it means—because it happens to us too.

Frequently Asked Questions
The answers we give most often over the phone.

90 € per hour, billed on actual time spent. The diagnosis and the estimate are free: you know the cost before we touch your store.
