Jean C
About this gig
PrestaShop errors can break checkout, stop payments, slow down your store, or create problems after a module or version update. I troubleshoot and fix technical issues without rebuilding parts of the store that are already working.
I will help with PrestaShop bugs, module conflicts, checkout and cart errors, payment gateway issues, theme problems, failed upgrades, slow pages, API connections, forms, AJAX, JavaScript errors, PHP compatibility, cache, database configuration, and broken storefront features.
For upgrade work, I review version compatibility, modules, theme overrides, PHP requirements, and existing customizations before making changes. For speed issues, I focus on the actual bottleneck instead of applying random optimization settings. For API problems, I can review authentication, requests, responses, webhooks, and data flow where documentation and access are available.
Send me your PrestaShop version, the affected module or page, screenshots or error details, and the result you expect. I will assess the issue and apply the most practical fix with testing before handoff.
