Urgent e-commerce troubleshooting

A site that stops responding, a module that breaks a page, an order that won't validate: troubleshooting means pinpointing the exact source of the problem in the code or configuration, then fixing it without rebuilding everything.

What troubleshooting covers

Troubleshooting targets a specific, locatable problem: an application error, a conflict between two modules, a regression after an update, a server-side incident blocking access to the site. The goal is to get the shop working again, not to redo what already exists.

It's not a full audit or a redesign: if the diagnosis reveals a bigger problem than the reported incident, I say so clearly before committing more time, and I propose a separate scope for that work.

What I fix most often

  • 500 error or blank page after a platform, theme or module update.
  • Checkout that fails or redirects wrongly after a change at the payment provider.
  • Conflict between two modules breaking the display or calculation on a page (cart, product page, order).
  • Overloaded or misconfigured server after a hosting migration or an unusual traffic spike.
  • Interrupted data import leaving the catalogue or stock in an inconsistent state.

How I work

  1. Access and reading the logs

    Access to the admin, server or code repository as needed, and reading the error logs to locate the source of the problem.

  2. Isolating the cause

    I reproduce the problem when possible, to tell a one-off cause apart from a structural issue.

  3. Targeted fix

    I fix the identified point, without changing what already works elsewhere on the site.

  4. Verification and report

    Testing the affected journey, then a written summary of what caused the fault and what was changed.

Frequently asked questions

What's the difference with a maintenance contract?
Troubleshooting is one-off, triggered by a problem you've noticed. Maintenance is ongoing follow-up aimed precisely at reducing how often that kind of incident happens. The two aren't mutually exclusive.
How is troubleshooting billed?
By the time actually spent on diagnosis and the fix, with a rough figure given as soon as the cause of the problem is identified.
Do you fix bugs in a third-party module I didn't buy through you?
Yes, as long as the module's code is accessible and editable. If the module is closed-source or depends on a failing third-party service, I flag it and point you towards an alternative.
Do I need to give you full access to the site?
Enough access to diagnose and fix, yes: admin, server or code repository depending on the nature of the problem. I state exactly what I need before starting.
Do you guarantee the problem won't come back?
I fix the identified cause, not a guess. If there's a structural reason it could recur, I say so explicitly rather than promising it's gone for good.
