If the WooCommerce Place Order button does nothing, first check whether it is disabled, whether validation stops checkout and whether the browser sends a request. Those are different failures. The button’s appearance alone cannot tell you whether an order or payment already exists.
If customers cannot complete a purchase, review the checkout repair service. Send the affected URL, payment method and exact symptom for an assessment; avoid asking customers to click repeatedly while the payment result is uncertain.
Identify classic checkout or the Checkout block
Classic checkout commonly submits through ?wc-ajax=checkout; the Checkout block uses the Store API checkout route, such as /wp-json/wc/store/v1/checkout. Inspect the request your store actually makes.
In the block, shipping or total calculations can temporarily disable Place Order. A disabled state is not automatically a broken click handler. Check what remains pending before force-enabling anything.
Define what “nothing” means
Test once in a private window and note whether the button changes appearance, the page scrolls to a field, the browser console records an error or the Network panel sends a checkout request.
Also check recent WooCommerce orders and the gateway dashboard. A customer may describe “nothing” when the page failed after payment processing. Protect against duplicate charges before asking them to retry.
Check whether the button can receive the click
Inspect whether the control is covered, disabled or associated with the expected checkout component. In classic checkout, check the form relationship; do not assume a classic form selector will diagnose the Checkout block. Use the element picker to identify an overlay intercepting the click.
/* Diagnostic only: do not leave this in production */
.suspected-overlay {
outline: 3px solid red;
pointer-events: none;
}Apply diagnostic CSS only in your own browser or staging. Permanently disabling pointer events can make consent or accessibility controls unusable.
Read the first browser error
Open Console, reload checkout and click once. Start with the first error generated after the page loaded. Later errors may be consequences.
Typical sources include checkout field plugins, theme scripts, address autocomplete, consent management and compressed JavaScript assembled by an optimisation plugin. A message naming jQuery, an undefined object or a blocked script gives a better lead than deactivating every extension.
Confirm whether Content Security Policy or a browser extension blocked a required file. Repeat in a clean browser profile before changing the store.
Inspect validation and required fields
WooCommerce may refuse submission because a required field is invalid, while CSS hides the error or scroll position. Inspect fields with aria-invalid="true" and error containers near the top of checkout.
Custom fields need a unique name, a valid value and matching server-side validation. Test addresses, phone formats and postcode rules appropriate to the selected country. Do not remove validation globally just to make one test pass.
Confirm the submit event and request
In Network, filter for checkout and click Place order. No request means the failure remains in layout, JavaScript or client validation. A request that returns an error belongs to a different path: inspect its status and response rather than the button.
If the final submission starts but the interface never finishes, follow the checkout-keeps-loading diagnosis and read its response before changing the click handler.
If custom JavaScript handles the event, look for code that calls preventDefault() without later resuming checkout. Check conditional branches for payment methods or terms acceptance.
Isolate the responsible integration safely
Reproduce the store in staging with the same theme, checkout type and relevant data. Disable script combination first if generated bundles obscure the source. Then test one suspected extension or theme override at a time.
Changing to a default theme can prove the theme layer is involved, but it is not automatically the final repair. Identify the override or script conflict so the live design can remain intact.
Repair without weakening checkout
Correct the conflicting selector, event handler, overlay stacking, invalid field markup or script loading order. Restore any required consent, fraud or payment control after testing. Avoid snippets that force-enable the button continuously; they bypass symptoms and can permit incomplete orders.
Clear only the relevant asset cache and confirm the new file reaches an anonymous visitor.
Verify customer paths after the fix
Agree a test method before testing: staging and the gateway sandbox where supported, with clearly identified test orders. Check guest and account checkout, mobile and keyboard interaction, validation errors and the active payment methods. Verify the expected order status, transaction result, stock and confirmation for that method; an unpaid order does not have the same expected state as a completed payment.
Before any live test, agree who authorises the charge and handles its consequences. Recurring checks should record failures and expected outcomes without silently creating real sales.
What to send for a checkout assessment
Send the URL, device, checkout type, payment method, approximate time and last update. Say whether the button stays disabled, shows an error or sends a request. Include a redacted screenshot or relevant log excerpt. Never send card numbers, passwords or a full browser-session export.
The repair process explains assessment, scope and approval. Request an assessment of the failed checkout if you cannot isolate the fault or reconcile the order and payment.
