Common bugs we fix

The WooCommerce errors that bring down stores

These are the real symptoms and error strings we see most often on WooCommerce + WordPress. If yours isn’t listed, it almost certainly belongs here too — report it and we’ll diagnose.

  • “There has been a critical error on this website”

    WordPress’ fatal-error handler hiding the real PHP error. We read wp-content/debug.log + Site Health, find the failing plugin or theme, and fix the actual fatal.

  • White screen after a plugin or theme update

    The classic WSoD after WooCommerce or a plugin auto-updates. We bisect by deactivating plugins on a clone, isolate the culprit, then patch the conflict instead of just rolling back.

  • Fatal error: Allowed memory size exhausted

    PHP memory exhausted on import, cron, or a heavy report. We trace the runaway query or loop, raise WP_MEMORY_LIMIT safely, and stop the leak at the source.

  • Checkout not completing / order stuck on pending

    Customers click Place Order and nothing happens, or orders hang on “Pending payment”. We debug the WooCommerce checkout AJAX, gateway callback, and order-status webhook end to end.

  • Payment gateway returns a 500

    Stripe, PayPal, or a custom gateway throwing a 500 on the callback / IPN. We inspect the gateway logs, fix the API/webhook handler, and confirm a real test order completes.

  • Cart fragments AJAX failing (quantity not updating)

    The mini-cart count or totals don’t refresh because ?wc-ajax=get_refreshed_fragments 403s or a cached page poisons the nonce. We fix the fragment cache + nonce mismatch.

Stuck specifically at payment? See WooCommerce checkout bug fixing. Not a store at all? We also fix plain WordPress critical errors.

How it works

Report to fixed — five steps, on a clone first

We reproduce on staging, bisect the conflict, and only deploy to live once the fix passes a regression check. You approve the cutover.

  1. 01

    Report

    You send the symptom, the exact error string, and store + WooCommerce versions through the form. We confirm scope and the urgency tier within the hour.

    Hour 1
  2. 02

    Reproduce

    We pull a clone (or your staging) and reproduce the bug there first — never debugging on the live store. Full DB + files snapshot taken before anything is touched.

    Hour 1–3
  3. 03

    Root-cause

    Plugin-conflict bisect: deactivate everything, re-enable one by one, read debug.log + query monitor until the true culprit and root cause are pinned, not just the symptom.

    Same day
  4. 04

    Fix + regression test

    Patch the actual cause — a hook conflict, a snippet, a gateway handler, a memory leak — then run a regression check so the fix holds and nothing else breaks.

    Same / next day
  5. 05

    Deploy + verify

    Ship to live in a low-traffic window, place a real test order or repeat your exact steps, and hand over a short written root-cause + prevention note.

FAQ

Straight answers about fixing WooCommerce bugs

How much does it cost to fix a WooCommerce bug?

Fixed prices, no hourly surprises. A single, well-defined bug starts at $99 (Quick Fix, ~4h @ $25/hr, turned around in 24–48 hours). A batch of bugs or one hard root-cause is the $499 Bug-Fix Sprint (~20h @ $25/hr). If your store is down or breaks repeatedly, the Emergency / Retainer tier is custom — including a $2,499 stabilization sprint (~100h @ $25/hr) for a store that keeps falling over. You get the price before any work starts.

How fast can you fix a critical WooCommerce error?

Emergency tickets (store down, checkout dead) get a senior developer within 4 hours, often inside the hour. A typical well-defined bug is reproduced, root-caused and shipped in 24–48 hours. Speed depends on access: with staging or live admin + SFTP ready, we move immediately; if we have to arrange access first, add that time. The single biggest accelerator is pasting the exact error string from wp-content/debug.log in your report.

My site shows “There has been a critical error on this website” — can you fix it?

Yes. That generic message is WordPress’ fatal-error handler hiding the real PHP error. We enable WP_DEBUG_LOG, read the actual fatal in wp-content/debug.log, and trace it to the failing plugin, theme, or snippet — usually a function conflict or an incompatible update. Then we fix the real cause rather than just deactivating the plugin and leaving your store missing a feature.

I get a white screen after updating a plugin or WooCommerce — what now?

That is the classic White Screen of Death after an auto-update. We pull a clone of your site, bisect the plugins — deactivate everything, then re-enable one at a time — until the conflicting plugin or theme is isolated. We then patch the actual incompatibility (a removed hook, a changed function signature, a PHP version mismatch) instead of permanently rolling back, so you keep the update and a working store.

How do you fix “Fatal error: Allowed memory size exhausted”?

That error means a PHP process ran out of memory — common during imports, large reports, or a runaway cron. We do two things: (1) trace why memory blew up (an unbounded query, an infinite loop, a leaking plugin) and fix the source, and (2) raise WP_MEMORY_LIMIT / PHP memory_limit to a safe value as a backstop. Just bumping the limit without finding the cause only delays the next crash, so we always do both.

My WooCommerce checkout isn’t completing / orders are stuck on pending — why?

Usually one of three things: the checkout AJAX (?wc-ajax=checkout) is failing silently, the payment gateway callback / webhook isn’t reaching your store, or an order-status hook is throwing. We debug the full chain — browser console, WooCommerce logs under WooCommerce → Status → Logs, and the gateway’s IPN/webhook — then fix the broken step and confirm a real test order completes end to end before we hand back.

My payment gateway returns a 500 error — can you debug it?

Yes. A 500 on a Stripe, PayPal, Mollie, or custom gateway callback almost always traces to the webhook/IPN handler — an expired API key, a changed API version, a malformed response, or a PHP fatal inside the handler. We read the gateway logs and the server error log, fix the handler, and verify with a real test transaction that the order is created and marked paid correctly.

My cart count / mini-cart doesn’t update — is that a bug you fix?

Yes — that’s the WooCommerce cart fragments AJAX failing. The ?wc-ajax=get_refreshed_fragments request returns a 403 or stale nonce, usually because a page-cache plugin (or a CDN like Cloudflare) is caching the cart fragment or the nonce. We fix the cache exclusion, the nonce mismatch, or disable fragments where they hurt performance, so the quantity and totals refresh instantly again.

Can you fix it without breaking my live store?

Yes — that’s the whole method. We reproduce and fix on a clone or your staging site first, never on live. Before any change, we take a full database + files snapshot. The fix is only deployed to production after it passes a regression check, and we ship it in a low-traffic window so even an unexpected hiccup has minimal impact. You approve the cutover.

Do you work on staging or directly on live?

Staging by default. If you already have a staging environment, we use it; if not, we spin up a clone. We only touch live for the final, tested deploy — and for true emergencies where there is no clone available, we work live but always take a snapshot first and change one thing at a time. Tell us in the form which access you have (staging, live admin + SFTP, or need to arrange) and we’ll plan around it.

Do you fix bugs that appeared after a WooCommerce or WordPress update?

Yes — post-update breakage is the most common ticket we get. WooCommerce core updates, a PHP version bump, or a plugin auto-update can break a theme hook, a custom snippet, or another plugin. We bisect to find exactly what the update changed, then update your code to be compatible — so you stay on the secure, current version instead of being stuck on an old one. This is the same work covered on our WordPress bug fixing page for non-Woo sites.

Is there a guarantee the bug stays fixed?

Yes. Every fix ships with a written root-cause note and a regression check, and the Bug-Fix Sprint includes 7 days of coverage — if the same bug resurfaces in that window, we fix it again at no charge. If the symptom you saw turns out to be several separate bugs, we tell you upfront and re-quote rather than billing silently. For stores that keep breaking, the retainer tier puts a developer on standby so the next fatal is handled before customers notice.

Store down right now?

Send the symptom and the exact error. A senior developer starts triage within 4 hours — and your live store stays safe the whole time.
