I will fix prestashop ecommerce website bugs update upgrade fix prestashop store error

About this gig
Is your PrestaShop store throwing errors, crashing at checkout, or stuck on an outdated version? Every hour it stays broken, you're losing real money.
I specialize exclusively in PrestaShop bug fixes, error resolution, core upgrades, and module conflicts. Not a generalist. Not a "I'll figure it out" freelancer. I've resolved 500+ PrestaShop issues across versions 1.6, 1.7, and 8.x for stores in 30+ countries.
What I fix:
- White screen / fatal errors after update
- Checkout broken, cart not working, payment failures
- Module conflicts and hook errors
- Slow store performance and database issues
- Theme display bugs and responsive breaks
- Admin panel crashes and 500 errors
Every fix includes a root cause explanation so you understand what went wrong, not just that it's fixed. No black-box patching. No shortcuts that break something else tomorrow.
Your store is your business. I treat it that way.
Message me before ordering if you're unsure which package fits your issue. I respond within 2 hours.

FAQ
Will you fix my store without taking it offline?
Yes. I work directly on your live server using careful file-level edits and always back up before touching anything. For complex upgrades, I recommend a 30-minute maintenance window — but most bug fixes require zero downtime.
What if the bug comes back after you fix it?
All packages include a revision period. If the exact same issue reappears within the covered window, I fix it at no extra charge. I also provide a short written summary of what caused it so you can avoid it recurring.
I don't know my PrestaShop version — can you still help
Absolutely. Just share your admin login and I'll identify the version, diagnose the issue, and recommend the right fix myself. You don't need to be technical — that's what I'm here for.
Is it safe to share my store credentials with you?
Your security is a priority. All credentials should be shared through Fiverr's encrypted chat — never by email or external tools. I only access what's needed to fix the issue, and I recommend changing passwords after the work is complete as a best practice.
Can you upgrade my PrestaShop without breaking my theme or modules
Yes — and this is where most upgrades go wrong when done incorrectly. I audit your theme and modules for compatibility before upgrading, flag anything that needs attention, and perform the upgrade in a way that keeps your customizations intact. You won't wake up to a broken storefront.
