Most sites accumulate JavaScript console errors quietly over time — a plugin script conflicting with another, a deprecated function call, a missing file reference — that don’t necessarily break anything visible but degrade performance and cause intermittent feature failures; this is a systematic sweep to find and document them, distinct from chasing one specific broken feature. A single console error rarely causes a dramatic, obvious failure on its own — more often it’s a contributing factor alongside several others, which is why a systematic sweep tends to surface things that fixing one reported bug at a time would miss entirely.
A quick note before ordering
This is primarily a diagnostic and reporting service, not a guaranteed fix-everything engagement.
Some errors found may need a dedicated follow-up fix once we know what they are, particularly if they come from a plugin we don’t control the code of, and we’ll say so plainly in the report rather than promise a fix we can’t deliver safely.
Some errors trace back to a plugin’s own code rather than anything specific to your site, and in those cases the realistic options are usually a configuration workaround, an update from the plugin’s developer, or switching to an alternative — we’ll be upfront about which applies.
We also check whether an error is consistently reproducible or only shows up intermittently, since intermittent errors — often tied to a race condition between two scripts loading in a different order — take longer to pin down than one that fails the same way every time.
JavaScript console error sweep
A systematic sweep for JavaScript console errors across your site, tracing each to its source and fixing the straightforward ones.
- Full backup taken before we start
- If we can’t fix it, you get your money back
- We never ask for your own password
What we need from you
- The pages or key user flows you most want checked, such as checkout, contact forms, or key landing pages
- Which browsers matter most for your audience, if you have a preference
- Whether you want us to fix straightforward errors as we find them, or report everything first before any changes
This or something else?
| You want a systematic sweep across the site to catalogue console errors | This fix covers it |
| You have one specific known broken feature and want it fixed | A more specific, targeted fix for that feature |
| You want ongoing monitoring for new errors as they appear | A different, ongoing-monitoring service |
| The site is visibly broken right now | A specific fault diagnosis, this is for less obvious issues |
| You only want the report, not any fixes | This fix covers it, we’ll flag that preference upfront |
What we do
- Systematically test key pages and user flows across the browsers that matter to you
- Record every JavaScript console error encountered, with the page and browser it occurred on
- Trace each error to its source — a specific plugin, theme file, or third-party script
- Prioritise the list by likely real-world impact versus cosmetic noise
- Fix straightforward, low-risk errors directly where the cause is clear and safe to correct
- Deliver a plain-language report covering what was found, what was fixed, and what needs a follow-up decision
What is included
- A systematic console error sweep across the pages and flows you specify
- Each error traced to its likely source
- Straightforward, low-risk errors fixed directly
- A written report covering findings, fixes made, and anything needing further decision
Not included
- Fixing every error found, if some require a larger follow-up engagement or a decision from you first
- Ongoing monitoring after this sweep is delivered
- Rewriting a third-party plugin’s own code beyond a safe, minimal correction
- Performance optimisation beyond what naturally follows from fixing genuine script errors
Questions about this fix
Will this fix a specific problem I already know about?
If you tell us about it, we'll prioritise checking it specifically, though this service is built around a systematic sweep rather than one targeted fix.
What happens to errors you find but don't fix?
They go in the report with an explanation of what would be involved in fixing them, so you can decide whether to commission that as a follow-up.
Does a console error always mean something is actually broken for visitors?
No — some errors are genuinely harmless noise, which is exactly why the report prioritises by likely impact rather than treating every error as equally urgent.
Can you check on mobile browsers specifically?
Yes, if mobile matters most for your audience, tell us and we'll weight the sweep toward the browsers and devices that are actually relevant to your visitors.
Will fixing these errors speed up my site?
Sometimes, since a genuinely broken script can waste processing time retrying or failing, but this service isn't a dedicated performance fix — some errors have no measurable speed impact at all.

If this is the second time this year
A bad update breaking the site is a symptom of updates not being tested first. Care plans run every update on a staging clone before it reaches your live site, which is the actual fix for this happening again.
Your access, your rules
Create a separate admin account for us and delete it when we are done. For anything else, we get in touch and agree a method — never a form field on this site, never by reply to an email.
We back up first, always
Before anything is touched we take a full backup and keep it for 30 days. If a fix goes wrong, we put the site back exactly as it was.
If it is not what you bought
If the problem turns out smaller than what you ordered, we refund the difference. If it is bigger, we stop and send a quote before doing any extra work.
If we cannot fix it
You get back what we received. Diagnosis is on us — you only pay when the problem is actually solved. The payment processor takes its fee before the money reaches us, so we never hold it and it is not ours to return. That is true here as everywhere else.
If it comes back
Reply within seven days of delivery and we put it back on the bench at no cost. The fix is not finished until it holds.
What we are responsible for
If something goes wrong with a fix, our responsibility is limited to what you paid for it. We take a full backup first so mistakes can be undone, and we tell you before doing anything outside what you bought.
