Laravel & PHP Bug Fixing

Read the stack trace. Kill the bug.

500 errors, Class not found fatals, stuck queue jobs, migration SQLSTATEs, memory crashes, PHP 8.x TypeErrors. We trace the throw site, fix the root cause, and ship a regression test that keeps it dead. Emergency response under 4 hours.

  • Fixed on a branch you review — never pushed to main
  • Every fix ships with a regression test
  • Quick Fix from $99 · 14-day cover
Emergency triage in under 4h Branch + PR workflow
  • < 4h Emergency triage

    Production-down Laravel apps get a first responder on the stack trace within four hours of an emergency report.

  • 500+ Bugs squashed

    Across Laravel, Lumen, and raw PHP backends — from autoload fatals to gnarly N+1 query storms.

  • 100% Branch & PR workflow

    Every fix lands on a feature branch with a diff you review — nothing pushed straight to your main.

  • 14-day Regression cover

    Each fix ships with a test that pins the bug closed. Two weeks of free cover if it ever resurfaces.

Common bugs we fix

The Laravel & PHP errors we see every week

Real exceptions with real fixes. From the everyday Class not found to a queue that quietly stopped processing, this is the bread and butter. Most also apply to plain PHP backends and APIs — not just Laravel.

  • 500 | Server Error & uncaught exceptions

    The Ignition error page (or a blank 500 in production) hiding a stack trace nobody’s read. We trace the throw site, fix the cause, and turn debug back off safely.

    Symfony\Component\HttpKernel\Exception\HttpException
  • Class … not found (autoload / Composer)

    Wrong namespace, a forgotten composer dump-autoload, PSR-4 path mismatch, or a service container binding gone missing after a merge. We find the broken wire.

    Error: Class "App\Services\Foo" not found
  • Queue jobs failing / stuck

    Jobs piling up in failed_jobs, a queue:work daemon that died silently, serialization errors, or a Horizon supervisor that never restarted after deploy.

    Illuminate\Queue\MaxAttemptsExceededException
  • Migration errors (SQLSTATE)

    A migration that half-ran, a foreign-key constraint that won’t drop, or the dreaded index-length error on utf8mb4. We repair the schema state without nuking your data.

    SQLSTATE[42000]: Syntax error or access violation: 1071
  • .env / config cache broken after deploy

    The classic “works locally, 500s on the server” — a stale config:cache, missing APP_KEY, or env vars read inside cached config. We reset the cache chain the right way.

    RuntimeException: No application encryption key has been specified.
  • Memory exhausted & PHP 8.x fatals

    Allowed-memory-size crashes from loading a whole table into Eloquent, plus PHP 8 TypeError and deprecation fatals surfacing after an upgrade. We chunk, type, and patch.

    Allowed memory size of 134217728 bytes exhausted

Fix process

Five steps from stack trace to green

We reproduce before we touch your code, and you review every diff before it ships. No cowboy fixes on production.

  1. 01

    Report

    You paste the stack trace, the failing route or command, and how to reach the app. We confirm scope and an ETA in writing — no discovery fees.

    Minute 0
  2. 02

    Reproduce

    We reproduce the bug on staging (or a local clone of your repo) so we’re fixing the real failure, not a guess. Reproduction steps go in the ticket.

    First hour
  3. 03

    Root-cause

    We read the trace top-to-bottom — Telescope, logs, dd(), query log — until we find the actual cause, not just the symptom that threw.

    Same day
  4. 04

    Fix + regression test

    We patch on a feature branch and add a PHPUnit/Pest test that fails before and passes after, so the bug stays dead. You review the diff.

    24–48h
  5. 05

    Deploy + verify

    We deploy through your pipeline (or hand you a clean PR), clear the right caches, and verify in production with you watching the logs.

    On approval

FAQ

Laravel & PHP bug-fixing questions, answered straight

How much does it cost to fix a Laravel or PHP bug?

One well-defined bug starts at $99 (a Quick Fix, roughly 4 hours at $25/hr), turned around in 24–48 hours. A batch of bugs, or one gnarly root-cause that needs investigation plus regression tests, runs as a Bug-Fix Sprint at $499 (~20h @ $25/hr). For mission-critical apps that can’t go down, a stabilization sprint is $2,499 (~100h @ $25/hr) with an on-call retainer option. You see a fixed price before any work starts — never billed silently by the hour.

How fast can you fix a Laravel bug?

Emergencies (app down in production) get a first responder on the stack trace within 4 hours. A single well-scoped bug is typically fixed and tested within 24–48 hours. Deeper root-causes — an intermittent MaxAttemptsExceededException, a memory leak, an N+1 query storm — take a little longer because we reproduce, profile, and add a regression test, but you get a written ETA up front.

Can you fix it without breaking my live app?

Yes. We reproduce the bug on staging or a local clone of your repo first, then fix on a feature branch you review as a diff or pull request — nothing is pushed straight to main or deployed without your approval. Each fix ships with a PHPUnit or Pest regression test that fails before and passes after, so we know the patch works and doesn’t silently break something else.

Do you work on staging or live?

Staging or a repo clone whenever possible — that’s where we reproduce and fix safely. We only touch production for the final deploy-and-verify step, with you watching the logs, or by handing you a clean PR to merge through your own pipeline. If there’s no staging, we can stand up a quick local environment from your git repo and a sanitized database dump.

What access do you need to fix the bug?

At minimum: the full stack trace, the failing route or Artisan command, and either Git repo access or a staging URL. Helpful extras: read access to storage/logs/laravel.log, Telescope or Sentry if you use them, and your .env structure (you can redact secrets). For deploy-and-verify we need either pipeline access or someone to merge the PR. We work to least-privilege — no more access than the fix requires.

Why does my Laravel app show "500 | Server Error"?

A 500 means an uncaught exception was thrown and APP_DEBUG=false hid the detail. The real error is in storage/logs/laravel.log — common causes are a missing APP_KEY (No application encryption key has been specified), a stale config:cache after deploy, a database connection failure, or a thrown HttpException. We read the actual trace, fix the cause, and make sure debug mode is safely off in production afterward.

How do you fix "Class not found" / Composer autoload errors?

An Error: Class "App\Services\Foo" not found almost always means one of: a namespace that doesn’t match the file path (PSR-4), a forgotten composer dump-autoload after adding a class, a service-container binding lost in a merge, or a case-sensitivity mismatch that works on macOS but breaks on a Linux server. We trace the autoload map, fix the root cause, and add a test so the wiring stays intact.

My queue jobs keep failing or get stuck — can you fix that?

Yes — this is one of the most common Laravel production issues. Symptoms include rows piling up in failed_jobs, a MaxAttemptsExceededException, a queue:work daemon that died after a deploy and never restarted, or serialization errors when a job holds a model that no longer exists. We diagnose the supervisor/Horizon setup, fix the failing job logic, add retry/backoff where appropriate, and make sure workers restart automatically on deploy.

Can you fix a broken migration or SQLSTATE error?

Yes. Failed migrations are delicate because a half-run migration can leave your schema in an inconsistent state. Typical errors: SQLSTATE[42000]: ... 1071 Specified key was too long (the utf8mb4 index-length trap), foreign-key constraints that won’t drop, or a column that already exists. We repair the schema state and the migrations table without dropping your data, then make the migration safely re-runnable.

How do you fix "Allowed memory size exhausted"?

An Allowed memory size of 134217728 bytes exhausted almost always means too much data loaded into memory at once — usually Model::all() on a big table, an unbounded collection, or eager-loading that fans out. We replace it with chunk(), cursor(), or lazy collections, fix any N+1 queries feeding the leak, and only raise memory_limit as a last resort. The fix ships with a test on a representative dataset.

Do you fix bugs that appear after a PHP 8.x upgrade?

Yes — PHP 8 turns a lot of old leniency into hard fatals. Common post-upgrade breaks: TypeError from stricter type coercion, deprecation notices becoming errors, removed functions, and named-argument or constructor-property changes in dependencies. We work through the failing paths, patch the code (and bump or replace incompatible packages), and run your test suite green on the target PHP version before signing off.

Is there a guarantee on the bug fix?

Yes. Every fix ships with a regression test that pins the bug closed, and we include 14 days of free cover — if the exact same bug resurfaces in that window, we fix it again at no charge. We also fix on a feature branch you review, so you approve the change before it ever reaches production. We don’t guarantee unrelated new bugs, but we do guarantee the one we were hired to kill stays dead.
