Description

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 centres reducing ticket volume
  • Documentation hubs and internal company wikis
  • Developers building customer-facing knowledge portals

Live Demo.

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.

FAQ

If you don’t see your question answered below, please post it on the WordPress.org support forum. This is the quickest way to get help, as I check the forums daily. For more personalized assistance, I also offer premium paid support via email.

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 organise 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 organise 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.
