GutenKit 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 — the editor won't load or a block shows "this block has encountered an error and cannot be previewed" after a customization change, the GutenKit Template Library throws an error, styles apply in the editor but not on the frontend, or blocks vanished/broke after an update
B) Build with blocks — layout/section structure with the flexbox Container, content/interactive blocks (Advanced Accordion/Tab, Post Grid, Pricing Table, Countdown, Image Comparison), the Mega Menu and Nav Menu, Offcanvas, the 900+ template library, global colors/fonts
C) Show dynamic content — the Query Loop Builder (filter by post type/taxonomy/meta/author/date), Dynamic Content (bind block text to post meta/ACF/user/site fields), and Display Conditions (show/hide blocks by rule)
D) Capture leads — the built-in Mailchimp block (opt-in into a Mailchimp audience); note GutenKit has no full form builder
E) Pick or confirm a plan (Free / Personal / Professional / Agency, yearly or lifetime) or weigh which feature is Pro
F) Customize/automate — WordPress hooks/filters and reading/writing gutenkit/-namespaced block markup via the WordPress core REST API
Free or Pro? Free (WordPress.org) ships the core block set + the template library + flexbox Container + responsive editing. Mega Menu, Query Loop Builder, Dynamic Content, Display Conditions, One Page Scroll, Sticky Content, Glass Morphism, Advanced Tooltip, Google Map, and the advanced Parallax are Pro. Confirm the tier before promising a feature.
Skip-ahead rule: if the user's prompt already contains enough context, skip to Step 2.
Step 2 — Route or answer directly

If the question is GutenKit-specific, continue to Step 3.
Step 3 — GutenKit platform reference
Read references/platform-guide.md for the full platform reference — blocks/modules, the Mega Menu / Query Loop / Dynamic Content / Display Conditions features, pricing/plan gates, data model, integration recipes, and code examples. For WordPress hooks/filters and the WordPress REST API approach to gutenkit/-namespaced markup, read references/gutenkit-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.
"The editor won't load / a block shows 'encountered an error and cannot be previewed'" is the #1 reported issue. It typically appears right after a customization change or an update, and clears when GutenKit is deactivated — a JS conflict, a corrupted block, or a stale editor build. Update GutenKit, hard-refresh and clear browser + page cache, then bisect by disabling other plugins (and switching to a default theme) on a staging copy until the conflict surfaces. Back up before editing a live site.
The GutenKit Template Library erroring inside ElementsKit Lite is a known Wpmet-internal conflict. GutenKit and ElementsKit (both Wpmet) share a template-library handler; running mismatched versions throws a gutenkit-template-library error. Update both plugins to their latest versions and clear cache; if it persists, deactivate one to confirm the culprit, then re-enable on the matched version.
"Styles apply in the editor but not on the frontend" is a per-page asset/cache mismatch. GutenKit loads CSS/JS selectively per page — regenerate/clear any page/object/CDN cache and allowlist GutenKit's assets in any minify/combine plugin so the frontend matches the editor.
Plan gating drives most surprises. The core blocks, template library, flexbox Container, and responsive editing are free. Mega Menu, Query Loop Builder, Dynamic Content, Display Conditions, One Page Scroll, Sticky Content, Glass Morphism, Advanced Tooltip, Google Map, and advanced Parallax are Pro — and degrade if the license lapses. Treat pricing as best-effort/annual and confirm the tier.
Lead capture is thin. GutenKit ships a Mailchimp opt-in block but no full form builder — no webhooks, no conditional logic, no multi-step, no payment fields. For anything beyond a Mailchimp opt-in, pair a dedicated form plugin and route the sequence via /sales-email-marketing.
The automation surface is WordPress, not a hosted API. No GutenKit REST API, no outbound webhook, no Zapier app. Read/write block markup through the WordPress core REST API (blocks are gutenkit/-namespaced in post_content, Application-Password auth); deeper extension means WordPress hooks/filters against the rendered output.
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 plan-gated features and integration details that may be outdated.
A block showing "this block has encountered an error and cannot be previewed," or the editor failing to load, is the top reported problem. The frontend often still renders; deactivating GutenKit restores the editor. Treat it as a JS conflict / corrupted block / stale build — update, clear cache, bisect plugins on staging before touching a live site.
The GutenKit Template Library can error inside ElementsKit Lite (both are Wpmet plugins sharing a template-library handler). Keep both plugins on matched, current versions and clear cache; deactivate one to isolate if it persists.
Mega Menu, Query Loop Builder, Dynamic Content, Display Conditions, One Page Scroll, Sticky Content, Glass Morphism, Advanced Tooltip, Google Map, and advanced Parallax are Pro and stop applying if the license lapses — test on staging.
Style changes applying in the editor but not on the frontend is a per-page asset/cache issue. Clear page/object/CDN cache and exclude GutenKit's CSS/JS from minify/combine plugins.
No full form builder. GutenKit has a Mailchimp opt-in block only — no native form storage, webhooks, conditional logic, multi-step, or payment fields.
No hosted REST API, no outbound webhook, no Zapier app. Automate via the WordPress core REST API (gutenkit/ block markup in post_content) and WordPress hooks/filters.
No native A/B testing, heatmaps, or analytics. GutenKit builds pages; measurement needs a separate tool (VWO, Microsoft Clarity).
Free-vs-Pro block/module/template counts vary across sources — confirm the live feature matrix before promising a specific count on the free tier.

Examples
Example 1: Read and bulk-edit GutenKit block markup programmatically
User: "I want to update the CTA text inside a GutenKit Button across 30 landing pages from a script. Is there an API?"
Approach: There's no GutenKit REST API — use the WordPress core REST API. GutenKit blocks are gutenkit/-namespaced block markup in each post's content field, so authenticate with an Application Password, GET the post content with context=edit, transform the <!-- wp:gutenkit/... --> markup string (not the rendered HTML), and POST it back. Pull the cURL/Python snippets from references/gutenkit-api-reference.md and test on staging first.
Example 2: My GutenKit editor stopped loading after I added a block
User: "After I added a GutenKit section, the editor shows 'this block has encountered an error and cannot be previewed' and won't load — but the live site is fine."
Approach: This is the top reported GutenKit issue. The frontend rendering while the editor breaks points to a JS conflict, a corrupted block from that edit, or a stale editor build. Update GutenKit to the latest version, hard-refresh and clear browser + page cache, then on a staging copy disable other plugins (and switch to a default theme) one at a time to isolate the conflict; if a single block is corrupt, remove/re-add it. If you also run ElementsKit, make sure both Wpmet plugins are on matched current versions. See Troubleshooting.
Example 3: Which plan do I need for a mega menu and dynamic post listings?
User: "I want a multi-column mega menu in my header and a blog grid that filters by category and pulls the post's ACF subtitle. What tier?"
Approach: All three are Pro. The Mega Menu, the Query Loop Builder (filter by category/taxonomy), and Dynamic Content (binding to an ACF field) are Pro-gated — the free tier covers the core blocks and template library but not these. Pricing is best-effort/annual (Personal/1-site ~$39, Professional/5-site ~$79, Agency/unlimited ~$149, with lifetime options); confirm current tiers and site counts in references/platform-guide.md, and warn that Pro features degrade if the license lapses.
Troubleshooting
A GutenKit block shows "encountered an error and cannot be previewed" / the editor won't load
Symptom: After a customization change or an update, a block can't be previewed or the block editor screen fails to load; deactivating GutenKit lets the editor load again. The published frontend is unaffected.
Cause: A JavaScript conflict with another plugin/theme, a corrupted block from the last edit, a stale editor build/cache, or (if ElementsKit is installed) a version mismatch between the two Wpmet plugins.
Solution: Update GutenKit (and ElementsKit, if present) to the latest version; hard-refresh and clear browser + page/object cache; on a staging copy, deactivate all other plugins and switch to a default theme, then re-enable one at a time to find the conflict. If one block is the culprit, delete and re-insert it. Keep a backup before editing live.
The GutenKit Template Library throws an error (often inside ElementsKit)
Symptom: Opening the GutenKit template/pattern library shows an error (e.g. a gutenkit-template-library error), sometimes surfaced while using ElementsKit Lite.
Cause: GutenKit and ElementsKit (both Wpmet) share a template-library handler; mismatched plugin versions, a failed library asset load, or a server/firewall blocking the library request break it.
Solution: Update both GutenKit and ElementsKit to their latest versions and clear cache; confirm the server can reach the Wpmet template endpoint (no aggressive firewall/security-plugin block). If it persists, deactivate one of the two plugins to confirm the culprit, then re-enable on the matched version; report a reproducible case to Wpmet support.
Block styles look right in the editor but not on the published page
Symptom: A color, spacing, or layout change looks correct in the editor but the live page doesn't reflect it.
Cause: GutenKit loads CSS/JS selectively per page; a caching/CDN layer is serving old assets, or a minify/optimization plugin stripped or reordered GutenKit's assets.
Solution: Clear page/object/CDN cache; allowlist GutenKit's CSS/JS in any minify/combine plugin; re-check in an incognito window to rule out the browser cache. If only some blocks are affected, edit and re-save the page to regenerate its assets.
