Searching Advanced Forms for ACF

    Why is my success message not showing after submission?

    Symptom: A visitor submits a form and never sees the success/confirmation message. The page reloads to its pre-submission state, shows the default page content, or otherwise skips the post-submission block entirely.

    The usual culprit is page caching. Advanced Forms renders the confirmation by re-rendering the same page in its “just submitted” state — so if a cache layer is serving a stored copy of the page, the visitor never sees the post-submission response, only the pre-cached version of the form. Less common causes are a theme template overriding the form’s container before the success block can render, or a redirect display argument pointing to a URL that doesn’t include the form (and therefore has no success block to show).

    You’ve got two practical fixes — pick whichever fits your setup better.

    Disable caching on the form’s page

    Section titled “Disable caching on the form’s page”

    Exclude the page that contains the form from page caching. Where you configure that depends on what’s doing the caching:

    • A caching plugin (WP Rocket, W3 Total Cache, LiteSpeed Cache, WP Super Cache, etc.) — each has a “never cache these pages / URLs” setting. Add the form’s page URL there.
    • Server-level caching (LiteSpeed, Varnish, NGINX FastCGI cache, host-managed full-page cache like Kinsta/WP Engine/SiteGround) — the plugin settings can’t always reach this layer. Ask your host’s support to exclude the page, or use whatever cache-exclusion mechanism their control panel exposes.
    • A CDN with HTML caching enabled (Cloudflare APO, Bunny, etc.) — exclude the URL from edge HTML caching too.

    If you’re not sure which layer is caching the page, load it in a private/incognito window right after submitting in another browser. If the form still looks unsubmitted there too, the page isn’t being served from cache and the cause is elsewhere — most likely a theme template wrapping or replacing the form’s container before the success block renders.

    Or: redirect to a dedicated thank-you page

    Section titled “Or: redirect to a dedicated thank-you page”

    The cleaner option in a lot of cases is to sidestep the issue entirely — send the visitor to a separate “thanks for your submission” page after they submit. The form’s page can stay cached, and the thank-you page is just a plain static page with no form on it, so caching doesn’t get in the way.

    Create the thank-you page in WordPress, then pass its URL to the redirect display argument when you render the form. Advanced Forms will send the visitor there immediately after a successful submission.

    This also gives you a cleaner UX moment — a dedicated page where you can thank the visitor properly, set expectations about what happens next, link to related resources, or fire off conversion tracking — rather than relying on an inline confirmation block to do all of that work.
