Related Articles : Display related articles at the bottom of KB articles based on categories and tags.

Pro features
Knowledge Base Pro enhances the plugin with advanced features for larger documentation sites, including ratings and feedback, a help widget, a powerful custom permalinks engine, premium layouts, enhanced TOC surfaces, and additional admin tools.
Article Rating & Feedback System : Collect binary or 5-star feedback with optional follow-up questions, admin alerts, Bayesian sorting, and GDPR-friendly tracking modes.
Help Widget : Offer an in-app support hub with live search, suggested articles, and a contact form inside a floating assistant.
Custom Permalinks Engine : Craft advanced URL structures for articles, sections, tags, and products using dynamic placeholders.
Knowledge Base Homepage Mode : Display the Knowledge Base on your site homepage. The Knowledge Base URL becomes the homepage and the Knowledge Base archive URL redirects to the homepage.
Enhanced Table of Contents : Three Pro TOC delivery surfaces — a sidebar widget that renders the TOC for the current article, a Gutenberg block to insert the TOC inline, and a floating/sticky panel that follows the reader down the page.
Advanced Admin Tools : Control knowledge base caching with expiry settings, on-demand cache clearing, and other productivity enhancements.
Documentation Layout Mode : Transform any KB page into a three-column docs site with a sticky section-tree sidebar on the left, article content in the center, and an “On this page” TOC rail on the right. Collapsible accordion navigation adapts to the current product, section, or article automatically.
Section Tree Block & Widget : Display a context-aware hierarchical navigation tree of your KB products, sections, and articles anywhere — as a Gutenberg block or a classic sidebar widget. The tree collapses and expands sections with an accessible accordion, and highlights the current page automatically.
GitHub Integration : Sync markdown documentation from a GitHub repo. Push changes via webhooks and articles are created or updated automatically. YAML frontmatter controls slug, title, products, and sections.
Article Export & Import : Export all Knowledge Base articles as a Markdown ZIP (with YAML frontmatter), a SQL INSERT dump, or an XLSX metadata spreadsheet. Re-import Markdown ZIPs to restore or migrate articles, with automatic taxonomy mapping and overwrite/skip control.
Ask the Docs (beta) : Visitors ask a question in plain language and get a short answer drawn only from your published articles, with links to the sources. Uses the AI provider you connect under Settings > Connectors in WordPress 7.0 or later, with answer caching, per-visitor and daily limits, and a Content gaps report of unanswered questions.
Key Concepts
Articles: Custom post type wz_knowledgebase : your FAQs, how-to guides, and documentation.
Products: Custom taxonomy wzkb_product : link articles to one or more products.
Sections: Custom taxonomy wzkb_category : organize content neatly into categories.
Tags: Optional wzkb_tag taxonomy: make finding content even easier.
Multilingual sites
Knowledge Base works with WPML, Polylang and TranslatePress. TranslatePress translates the knowledge base with the rest of the page, including REST responses, related articles, and live-search suggestions. No additional Knowledge Base configuration is needed for TranslatePress.
Rendered output and REST caches are separated by language, preventing cached content and links from being reused across languages.

Frequently asked questions.
Why are Knowledge Base pages giving 404 errors?
Flush permalinks! Go to Settings > Permalinks and just click Save Changes .
What shortcodes are available?
Check the full shortcode guide here: Knowledge Base Shortcodes .
Can I override templates?
Absolutely! Copy these files into your theme or wp-content/knowledgebase/templates/ :
single-wz_knowledgebase.php
archive-wz_knowledgebase.php
taxonomy-wzkb_category.php
wzkb-search.php
Or .html versions if you are using a block theme.
How do I change the article or section order?
Use a plugin like Intuitive Custom Post Order to easily drag and drop posts, sections or tags to display them in a custom order.
Can I use this as a help center or wiki?
Yes! Knowledge Base works equally well as a help center, wiki, FAQ site, or documentation portal. Use sections to organize topics and products to separate different areas of your documentation.
Does it support multiple products or projects?
Yes. Enable Multi-Product mode via the Setup Wizard to organize articles under separate Products, each with their own sections and sub-sections.
Is it compatible with page builders like Elementor or Divi?
Yes. You can use the [knowledgebase] shortcode in any page builder. The plugin also provides Gutenberg blocks for block-based themes.
Can visitors search the knowledge base?
Yes. The plugin includes a built-in search form (via the [wzkb_search] shortcode and a Search block for Gutenberg) with optional live AJAX suggestions. You can enable or disable live search from the plugin settings. The Pro version also adds a floating Help Widget with live search and suggested articles.
Is it compatible with WPML or Polylang?
Yes. Knowledge Base has built-in support for both WPML and Polylang:
Articles, sections, products, and tags are all translatable. WPML uses wpml-config.xml (bundled with the plugin) for automatic configuration. Polylang auto-detects the public post type and taxonomies.
Widgets (Articles, Sections, Products) translate stored term IDs to the current language automatically, so you can save a term ID in the default language and the widget will display the correct translation.
Archive URLs resolve to the language-aware URL via get_post_type_archive_link() , which both WPML and Polylang filter automatically.
Caching is language-aware — cached output is keyed per language so visitors never see content from the wrong locale.
Known limitations:
The Pro Custom Permalinks feature builds URL structures using home_url() . With WPML you may need to set the Language URL format to Directory (e.g. /en/ , /fr/ ) for custom permalink structures to resolve correctly per language.
The built-in search form posts to home_url( '/' ) — this is the standard WordPress search pattern and is handled correctly by both plugins’ URL routing.
How can I report security bugs?
You can report security bugs through the Patchstack Vulnerability Disclosure Program. The Patchstack team help validate, triage and handle any security vulnerabilities. Report a security vulnerability.
