Block themes define sitewide colours, fonts, and spacing centrally in a theme.json file, and when a page builder or older customisation method also tries to set those same global values, WordPress has to decide which source wins — and it doesn’t always decide consistently, producing styling that looks right in one context and wrong in another for no edit you can point to. This kind of drift is particularly disorienting because nothing about it looks like an obvious bug — every individual value can appear perfectly reasonable in isolation, and it’s only the disagreement between sources that actually causes the problem.
Before you buy, one quick look
Read-only. Compare a colour or font setting in the Site Editor’s Styles panel against the same element’s appearance in the block editor and on the live page — three places that should agree.
Finding a mismatch between any two of those three confirms a genuine conflict between style sources, rather than a single simple styling mistake, and it’s useful to note exactly which places disagree before ordering.
Also worth checking is whether the disagreement is consistent every time you look, or seems to shift, since an inconsistent result usually points toward a caching layer rather than the underlying settings themselves.
Global styles & theme.json conflict fix
Your theme.json settings and Elementor's or another builder's global styles are fighting for control of colours, fonts, or spacing. We resolve the conflict.
- 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?
| theme.json settings and another style source disagree across editor and live page | This fix covers it |
| Elementor’s Global Colors or Fonts specifically are being overwritten | A different, Elementor-specific global-style fix |
| A single element’s styling is simply wrong, no conflicting sources involved | A different, narrower display-fault diagnosis |
| The site uses a classic, non-block theme with no theme.json file | This fix likely doesn’t apply; a different diagnosis fits better |
| You want theme customizations moved into a proper child theme, not this conflict resolved | Customizer CSS migration to child theme |
What you are seeing
- Colours, fonts, or spacing appearing differently across editor and live page
- Global style settings that don’t reliably apply across all blocks or templates
- The inconsistency appearing after a theme update or a builder plugin installation
- Some templates or block types reflecting the correct styling and others not
- No single edit you can identify as having caused the drift
Common causes
- A page builder plugin also writing sitewide style values that theme.json defines
- A theme update changing theme.json defaults without accounting for existing customisations
- Cached style output serving values from before a global style change
- Block-level style overrides taking precedence inconsistently over global settings
- A child theme’s own theme.json partially, rather than fully, overriding the parent’s
What we do
- Compare style values across theme.json, any competing source, and the live output
- Identify exactly where the conflicting values originate
- Establish a single, clear source of truth for the styles in question
- Remove or reconcile the competing source so it no longer overrides unpredictably
- Clear relevant caches and confirm consistent styling across editor and live page
- Check other global style values for the same latent inconsistency
What is included
- The conflicting style sources identified and reconciled
- A single, clear source of truth established for the affected settings
- A check for the same inconsistency in other global style values
- The pre-fix backup, kept for 30 days
Not included
- Redesigning your sitewide styles beyond resolving the conflict
- Migrating away from a page builder entirely, which is a separate service
- Fixing single-element styling issues unrelated to a genuine source conflict
- Ongoing monitoring for future theme or plugin updates
Questions about this fix
Which source should win, theme.json or the other tool?
That depends on how you actually want to manage your site's styles going forward, so we discuss it with you rather than assume — there's a genuine tradeoff either way.
Will this affect content I've already styled individually at the block level?
Individual block-level overrides are generally left alone, since this addresses the global, sitewide layer of conflict, not deliberate per-block customisation.
Could a theme update cause this again later?
It's possible if a future update changes theme.json defaults again, though understanding this conflict now makes it much faster to recognise and fix if it recurs.
Is this the same as the Elementor Global Colors and Fonts issue?
It's a related category of problem — competing sources of sitewide styling — but this specifically concerns theme.json and block-theme mechanics rather than Elementor's own settings.
Will I need to redo my site's styling from scratch?
No — we reconcile the conflict using your existing intended styling as the reference, not by starting your design over.

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.
