Kadence Blocks Platform Help
Step 1 — Gather context
If references/learnings.md exists, read it first for accumulated platform knowledge.
What are you trying to do?
A) Fix a broken state — editor blank/won't load, blocks or CSS not rendering on inner pages, custom/child-theme CSS not showing in the editor, a caching/optimization plugin broke styles, slow TTFB / high server load
B) Build with blocks — Row Layout/Section flexbox containers, Advanced Form, Gallery, Tabs/Accordion, Posts, Testimonials, Design Library patterns, Starter Templates
C) Use Pro/dynamic features — Advanced Query Loop, Dynamic Content (ACF/MetaBox/WooCommerce), Advanced Slider, Modal, Animate on Scroll, Custom Fonts, Kadence AI
D) Customize/automate — public hooks/filters (kadence_blocks_posts_query_args, kadence_blocks_pro_query_loop_query_vars, kadence_element_display), Advanced Form webhooks → Zapier/Make/CRM, WordPress REST API on block content
E) Pick or compare a plan (Free / Essentials / Pro / Elite, or standalone Kadence Blocks Pro) or weigh Kadence Blocks vs other block builders
Free or Pro? Free (WordPress.org, 20+ blocks). Pro adds Advanced Query Loop, Dynamic Content, Advanced Slider/Modal, the Design Library/Creative Kit, Kadence AI, and form webhooks. Pro is sold standalone or inside the unified Kadence bundles (Essentials/Pro/Elite).
Skip-ahead rule: if the user's prompt already contains enough context, skip to Step 2.
Step 2 — Route or answer directly
Problem domain
Route to
Funnel strategy, page structure, builder selection across tools (Spectra/GenerateBlocks/Elementor/SeedProd…)
/sales-funnel — Run: /sales-funnel {user's original question}
A/B testing methodology (Kadence Blocks has no native split testing)
/sales-vwo — Run: /sales-vwo {user's original question}
Email sequences/automation after a Kadence Advanced Form opt-in
/sales-email-marketing — Run: /sales-email-marketing {user's original question}
Growing the list, lead-magnet strategy
/sales-audience-growth — Run: /sales-audience-growth {user's original question}
/sales-checkout — Run: /sales-checkout {user's original question}
On-page/technical SEO beyond Kadence's schema/FAQ blocks
/sales-seo — Run: /sales-seo {user's original question}
If the question is Kadence-specific, continue to Step 3.
Step 3 — Kadence Blocks platform reference
Read references/platform-guide.md for the full platform reference — blocks/modules, pricing/plan gates, data model, integration recipes, and code examples. For the public hooks/filters list, the Advanced Form webhook flow, and the WordPress REST API surface on block content, read references/kadence-api-reference.md.
Answer the user's question using only the relevant section. Don't dump the full reference.
Step 4 — Actionable guidance
Focus on the user's specific situation.
Dynamic CSS regeneration is the #1 performance complaint. On high-traffic or WooCommerce sites, Kadence can regenerate block CSS per request and inflate TTFB. Fix: Kadence → Settings → General → CSS/JS set CSS output to External File (not inline), enable the built-in Performance tools, and let a page cache serve the generated assets. Confirm class-kadence-blocks-css.php isn't running uncached.
"Editor goes blank / won't load" is usually a JS conflict or a stale build. Update Kadence Blocks (+ Pro) first, hard-refresh, disable other editor-heavy plugins to isolate, and check the browser console. Do not enable SCRIPT_DEBUG on production to debug it.
"Custom/child-theme CSS won't show in the editor" — the block editor iframe doesn't auto-load your stylesheet. Enqueue it with add_editor_style() (or enqueue_block_assets) so it loads inside the editor, and regenerate Kadence's cached CSS after changes.
Plan gating drives most surprises. Free is 20+ blocks; Advanced Query Loop, Dynamic Content, Advanced Slider, Modal, Custom Fonts, the Design Library/Creative Kit, Kadence AI, and form webhooks are Pro. Confirm the tier before promising a feature; Pro features degrade when the license lapses.
No native A/B testing, heatmaps, or analytics. Pair with a separate tool (VWO, Microsoft Clarity) — Kadence only builds the page.
The real automation surface is WordPress hooks/filters + the WP REST API, not a hosted API. Form leads exit through the Advanced Form webhook (Pro) or the connected ESP integration — there is no outbound platform webhook beyond that.
If you discover a gotcha, workaround, or tip not covered in references/learnings.md, append it there.
Gotchas
Best-effort from research (2026-06) — review these, especially items about plan-gated features and integration details that may be outdated.
Dynamic block CSS can regenerate per request and slow TTFB on high-traffic/WooCommerce sites. Switch CSS output to an external file, enable the Performance tools, and serve generated assets from page cache.
The editor occasionally loads blank / won't let you edit. Usually a JS conflict or stale asset build — update Kadence, clear caches, and isolate other editor plugins; check the console.
Child-theme / custom CSS doesn't appear inside the block editor. The editor runs in an iframe; enqueue styles with add_editor_style() / enqueue_block_assets and regenerate Kadence's cached CSS.
Caching/optimization plugins can break Kadence styles or scripts (aggressive minify/combine/defer). Exclude Kadence's generated CSS/JS handles, then re-test.
Some blocks still depend on jQuery (e.g. the Tabs block has broken when jQuery was manually dequeued). Don't blanket-dequeue jQuery on pages using those blocks.
Advanced Query Loop, Dynamic Content, Advanced Slider, Modal, Custom Fonts, Design Library, Kadence AI, and form webhooks are Pro. The free plugin is block-building only; Pro features degrade when the license expires.
No native A/B testing, heatmaps, or analytics. Kadence builds pages; measurement needs a separate tool.

Examples
Example 1: Send an Advanced Form submission to a CRM via webhook
User: "How do I push Kadence form submissions into my CRM automatically?"
Approach: The Advanced Form webhook is the right surface (it requires Kadence Blocks Pro). On a Kadence Form, open Actions After Submit and check WebHook; on a Kadence Form (Adv), open Submit Actions and add WebHook. A Webhook Settings panel appears — paste your endpoint as the Webhook URL and use Map Fields to bind each form field to the payload key your CRM (or a Zapier/Make "Catch Hook") expects. Test with a temporary URL (e.g. webhook-test.com) before going live. For the exact menu path and field-id format (kadence-form-{id}), see references/kadence-api-reference.md.
Example 2: My site got slow after adding Kadence Blocks
User: "TTFB jumped on my WooCommerce store after I started using Kadence Blocks — what's going on?"
Approach: This is almost always dynamic CSS being regenerated per request (class-kadence-blocks-css.php). In Kadence → Settings → General → CSS/JS, set CSS output to External File instead of inline so the stylesheet is generated once and cached, enable the built-in Performance tools, and make sure a page cache is serving the assets. Re-test TTFB. See Troubleshooting and references/platform-guide.md for the full performance checklist.
Example 3: Which plan do I need for Dynamic Content and the Query Loop?
User: "I want to build a dynamic listing pulling ACF fields into blocks — what tier?"
Approach: Advanced Query Loop and Dynamic Content are Pro — the free plugin can't do them. Kadence Blocks Pro (standalone, or inside the Essentials/Pro/Elite bundles) unlocks them, plus the Design Library and Kadence AI. Warn that Pro-gated features degrade if the license lapses, so test on staging. Confirm current tiers/prices in references/platform-guide.md (pricing is best-effort and annual).
Troubleshooting
Editor loads blank or won't let me edit
Symptom: Opening a page/post shows a blank editor or nothing loads, intermittently.
Cause: A JavaScript conflict with another plugin, or a stale/partial asset build.
Solution: Update Kadence Blocks and Kadence Blocks Pro to the latest version; hard-refresh and clear browser + page cache; deactivate other editor-heavy plugins one at a time to isolate the conflict; check the browser console for the failing script. Avoid enabling SCRIPT_DEBUG on production — it can expose dev assets and cause its own issues.
Site is slow / high TTFB after adding Kadence Blocks
Symptom: Slower TTFB or higher server load, especially on high-traffic or WooCommerce pages.
Cause: Kadence regenerating dynamic block CSS on every request without caching.
Solution: Set CSS output to External File (Kadence → Settings → General → CSS/JS), enable the built-in Performance tools, and ensure a page-cache plugin serves the generated assets. Confirm the CSS class isn't running uncached on every load.
Kadence styles broke after enabling a caching/optimization plugin (or custom CSS won't show in the editor)
Symptom: Blocks render unstyled/distorted after turning on minify/combine/defer, or your child-theme CSS doesn't appear inside the block editor.
Cause: The optimization plugin is stripping/deferring Kadence's generated CSS/JS, or the editor iframe never loads your stylesheet.
Solution: In the caching/optimization plugin, exclude Kadence's generated CSS/JS handles from minify/combine/defer, then regenerate Kadence's cached CSS and clear caches. For editor styling, enqueue your stylesheet with add_editor_style() (or hook enqueue_block_assets) so it loads inside the editor.
