I will fix outdated prestashop, upgrade, update and resolve module errors safely
Adrian Falk
About this gig
Is your PrestaShop store outdated, showing errors after an update, or incompatible with your PHP, hosting, modules or theme? A major upgrade is not a one click update. Poorly handled upgrades can break checkout, payments, products, orders, back office.
I specialize in PrestaShop upgrades and compatibility, helping store owners move to newer versions while resolving issues before, during and after the upgrade. Whether you are upgrading PrestaShop 1.6, 1.7, 8 or 9, recovering from a failed update, or facing incompatible modules, themes, overrides or PHP requirements, I investigate the cause and fix it.
WHAT I HANDLE:
- PrestaShop version upgrades and updates
- PHP, hosting and database compatibility
- Module, theme and override compatibility
- Custom code and configuration conflicts
- Fatal errors, blank pages and back-office issues
- Cart, checkout, payment, product and order problems
- Post upgrade troubleshooting
- Data checks
I take a compatibility first approach instead of simply changing the version number. The goal is a stable, tested store after the upgrade.
Need a reliable PrestaShop upgrade? Send your current version, target version and any errors before ordering.
