Fix Broken JavaScript

The Problem

A button doesn't do anything when clicked, a form won't submit, a slider is frozen, or a dropdown doesn't open — and the browser's console is showing a red error message you don't know how to read.

About this problem

Most front-end JavaScript bugs come down to one of a few things: a script failing to load at all (a wrong path, a plugin conflict, an ad blocker), a script running before the page element it needs exists yet, or two scripts stepping on each other (often jQuery conflicts, or two plugins both trying to control the same element).

It's especially common after adding a new plugin or widget, updating an existing one, or editing theme code directly without testing the specific interactive feature afterwards.

What's Included

• Reading the browser console to identify the actual JavaScript error and where it's coming from
• Tracing the error back to its real cause (a conflict, a loading order issue, a broken reference)
• Fixing the script or resolving the conflict so the feature works as intended
• Testing the fixed feature across the browsers you actually care about

What's NOT Included

• Writing new custom JavaScript features from scratch (that's a separate, scoped build)
• Fixing bugs in a paid plugin's own code — that's usually best raised with the plugin's support, though a workaround can often be found
• Ongoing maintenance as future plugin updates are installed

How It Works

1. Open the browser console on the affected page and reproduce the broken interaction to capture the exact error message and line.
2. Trace the error to its source — a missing dependency, a script loading in the wrong order, a conflicting variable name, or an element the script expects that isn't present yet.
3. Check for conflicts between scripts, particularly jQuery version mismatches or two plugins targeting the same element.
4. Apply a fix at the right level — correcting the script itself, adjusting load order, or scoping a conflicting script so it stops interfering.
5. Re-test the specific feature (and a couple of related ones) across the browsers that matter for your traffic.

In practice: you buy the service, send over whatever access or details the job needs, I investigate and do the work, and you confirm it's resolved before we call it done.

Frequently Asked Questions

Why doesn't my button do anything when I click it?

This is almost always a JavaScript error stopping the script attached to that button from running at all — the browser console will usually show exactly where it's failing.

What does a 'jQuery is not defined' error mean?

It means a script is trying to use jQuery before jQuery itself has loaded, usually because of a loading-order problem or a conflict between plugins each trying to manage their own version.

Can one broken script break my whole website?

It can break every feature that comes after it in the loading order, even unrelated ones, because browsers generally stop running a script file the moment they hit an error partway through it.

Why does a feature work on my computer but not for visitors?

Often a caching issue (you're seeing an old cached version), a browser extension interfering only on your machine, or a feature that behaves differently across browsers — all worth ruling out separately.

Do I need to know how to code to get a JavaScript bug fixed?

No — you just need to describe what's supposed to happen and what's happening instead; the actual console errors and code are read and fixed as part of the service.

Will updating my plugins fix JavaScript errors automatically?

Sometimes, if the bug was already fixed upstream, but it can also introduce new conflicts — updates are worth testing on a staging copy first if the site is business-critical.
