From the developer

Ajay's own description of Knowledge Base, lightly tidied.

Knowledge Base makes building a knowledge base or FAQ for your WordPress site easy, fast, and scalable.

Whether you need a simple FAQ page, a full self-service help center, or a structured multi-product wiki, Knowledge Base scales to fit. Organize articles into products and sections, customize permalinks, and let your customers help themselves: no coding required.

Perfect for:

  • Multi-product companies managing multiple help centers
  • SaaS platforms with self-service documentation portals
  • Ecommerce support centers reducing ticket volume
  • Documentation hubs and internal company wikis
  • Developers building customer-facing knowledge portals

Powerful features available in the Free version

  • Unlimited Knowledge Bases: Support as many products as you like, with unlimited sections and sub-sections.
  • Beautiful, Responsive Layouts: Ships with clean templates powered by the Responsive Grid System.
  • Customisable Permalinks: View your KB at /knowledgebase/ by default or change the base slugs for articles, sections, products, and tags. Advanced custom permalink structures with dynamic placeholders are available in Pro.
  • Shortcodes + Gutenberg Blocks: Add KB listings anywhere using [knowledgebase] or use the Knowledge Base block.
  • Built-in Breadcrumbs: Improve UX and SEO with breadcrumb navigation.
  • Widgets Included: WZKB Articles, WZKB Sections, WZKB Products, and WZKB Breadcrumbs widgets.
  • Built-in Caching: Speed up your Knowledge Base without extra plugins. Configurable cache expiry settings are available in Pro.
  • Multilingual Ready: Full WPML and Polylang compatibility — translate articles, sections, products, and tags; language-aware caching and widgets included out of the box.
  • Auto Table of Contents: Automatically generate a linked Table of Contents from article headings, with configurable depth and minimum heading threshold.
  • Live Search Suggestions: Show accessible AJAX search suggestions as visitors type in the Knowledge Base search form.
  • Related Articles: Display related articles at the bottom of KB articles based on categories and tags.
  • Alerts: Add attention-grabbing alert boxes with the [kbalert] shortcode or Alerts block.
  • Settings Export & Import: Back up and restore all plugin settings as a JSON file. Sensitive values (API keys, webhook secrets) are automatically stripped on export and never overwritten on import.

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.
  • Premium Layout Pack: Unlock seven additional frontend styles (Modern, Minimal, Boxed, Gradient, Compact, Magazine, Professional).
  • 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.

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.

Contribute

If you have an idea, I’d love to hear it. WebberZone Knowledge Base is also available on Github. You can create an issue on the Github page or, better yet, fork the plugin, add a new feature and send me a pull request.
