A plugin conflict happens when two plugins each expect to be the only one doing something — registering the same function, hooking the same action, loading a script the other assumes it controls — and the result can be anything from a blank error to a feature that simply stops working with no message at all. Finding which two plugins are involved is most of the job.
Before you buy, one distinction worth making
Is there an actual error — a white screen, a message naming a fatal error — or is something just behaving wrong with no error shown at all?
Those are genuinely different problems even though both get called a “plugin conflict”: an error usually narrows to one specific plugin quickly; a silent behavioural clash between two plugins that each work fine alone takes longer to isolate, and it’s useful to know which one you’re dealing with before you order.
If you can reproduce the problem reliably — the same page, the same action, every time — that repeatability is worth mentioning too, since an intermittent conflict is diagnosed differently from one that happens consistently, and knowing which you’re dealing with changes where the testing starts.
It’s also worth thinking back to what changed recently — a new plugin, a theme update, a hosting change — even if it doesn’t feel connected. Conflicts often sit dormant until something else shifts the balance, so the trigger isn’t always the plugin that’s now misbehaving.
Plugin conflict diagnosis & resolution
Something stopped working with no error message, and you suspect two plugins are interacting badly. We isolate the specific conflict and fix it without breaking either plugin's own features.
- Full backup taken before we start
- If we can’t fix it, you get your money back
- We never ask for your own password
This or something else?
| Something behaves wrong with no error message, two plugins suspected | This fix covers it |
| A specific error message naming a plugin or fatal error | Plugin fatal error isolation |
| The conflict appeared right after activating one specific new plugin | Blank page after plugin activation |
| The conflict appeared right after an update, not a new activation | Plugin update failure resolution |
| You already know which two plugins conflict and just want it resolved | This fix covers it, at a smaller scope |
What you are seeing
- A feature that stopped working with no error message anywhere
- Two plugins each working correctly when the other is deactivated
- Behaviour that’s inconsistent — works on some pages, not others
- The problem appearing after installing a new plugin, with no direct error connecting the two
- Support for one plugin blaming the other, and vice versa
Common causes
- Two plugins registering the same JavaScript or CSS handle with different versions
- Both plugins hooking the same action at a priority that assumes they run first
- Overlapping functionality — two SEO plugins, two caching plugins — each asserting control
- A shared library or dependency loaded twice at different, incompatible versions
- One plugin’s output being modified or stripped by a filter the other plugin added
What we do
- Reproduce the behaviour and identify exactly what stops working and where
- Isolate the conflict by testing with plugins deactivated in a controlled sequence
- Identify the specific hook, script, or function both plugins are contending over
- Resolve the conflict — reordering priority, excluding a script, or a targeted compatibility fix
- Confirm both plugins’ own features still work correctly after the fix
- Re-test across the pages and scenarios where the conflict originally appeared
What is included
- The specific conflicting plugins and mechanism identified, not just patched around
- A fix that preserves both plugins’ functionality where possible
- Testing across the affected pages and scenarios
- The pre-fix backup, kept for 30 days
Not included
- Removing one of the plugins, without your agreement
- Fixing a plugin that’s simply broken on its own, unrelated to another plugin
- Ongoing conflicts introduced by future plugin updates
- Rebuilding functionality lost if a plugin genuinely has to be removed
Questions about this fix
Do I need to know which two plugins are involved before I buy?
No — narrowing that down is the diagnostic work itself. Telling us what you've already tried, if anything, saves time, but arriving with no theory at all is completely fine.
Could this be three plugins interacting, not just two?
Occasionally, yes, though two is far more common. We don't stop testing once we find one plausible pair if the behaviour doesn't fully resolve, since a three-way interaction needs a different fix.
Will you need to deactivate plugins on my live site to test?
Where possible we test on a staging copy or during low-traffic hours; deactivating a plugin briefly doesn't delete its data, so there's no lasting effect either way.
Both plugin developers say it's the other plugin's fault. Does that help?
A little, since it confirms the conflict is real and known, but it rarely says which specific hook or script is colliding — that detail is usually left to whoever is actually debugging it, which is what this covers.
Can this happen between a plugin and my theme, not two plugins?
Yes, the same kind of clash can happen between a plugin and a theme's own code, and we check for that too rather than assuming the cause is always plugin-to-plugin.

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.
