Common Problems & Fixes
Echo Knowledge Base search is not returning relevant results — basic keyword searches return no articles even though articles contain the keywords. How do I fix search?
Echo KB uses WordPress search with AJAX enhancement. If search returns no results: (1) verify articles are published (not draft) — unpublished articles are not searchable; (2) Echo KB uses the WordPress search API which requires the articles post type to be searchable — check Settings → Echo KB → Advanced and verify “Exclude from Search” is not enabled; (3) the AJAX search has a minimum character trigger — ensure the search query is long enough; (4) clear object and page caches; (5) if using a search plugin (Better Search, SearchWP), verify it indexes the Echo KB article post type.
Echo Knowledge Base article ratings (thumbs up/down) are not saving — clicking thumbs up/down does not record the rating. How do I fix ratings?
Article ratings use AJAX requests. Check: (1) the rating feature is enabled in Echo KB settings; (2) browser DevTools Console for JavaScript errors during rating click; (3) AJAX request in Network tab — verify the rating request reaches the server and receives a success response; (4) a security plugin may block the rating AJAX endpoint; (5) if users must be logged in to rate (configurable in Echo KB settings), verify the user is logged in when attempting to rate; (6) clear all caches.
Echo KB is displaying articles from all categories mixed together — the organized category structure is not showing. How do I configure category display?
Echo KB’s main page layout depends on the configured layout type. In Echo KB → Configuration → Main Page: (1) verify the layout is set to “Category Layout” or “Basic Layout” depending on preference; (2) articles must be assigned to Echo KB categories (not standard WordPress categories) — check article edit screens for category assignment; (3) the category order in the main KB page is configurable — drag categories in Echo KB → Categories to arrange them; (4) clear all caches after configuration changes.
Customization & Developer Notes
How do I change the visual appearance of the Echo Knowledge Base to match my theme?
In Echo KB → Configuration → Style, access the frontend visual editor. Choose from 26+ design templates as the starting point. Customize: header colors, background colors, article link colors, typography, button styles, and sidebar appearance. The visual editor shows a live preview as you adjust settings. For complete color customization, Echo KB provides CSS variable overrides in Configuration → Style → Custom CSS. Most visual changes can be made through the style editor without writing CSS.
How do I set up a tabbed knowledge base for multiple products using Echo KB?
Echo KB’s tabbed layout organizes documentation by top-level category into separate tabs. In Echo KB → Configuration → Main Page → Layout, select the “Tabs” layout option. Create top-level categories for each product (Product A, Product B, Product C). Each product category becomes a tab in the knowledge base. Sub-categories and articles are organized within each product tab. The tabbed layout works well for software companies with multiple products needing separate documentation sections.
Frequently Asked Questions
How does Echo Knowledge Base compare to BetterDocs?
Echo KB has more design templates (26+) and better free visual customization. BetterDocs has a more modern design aesthetic, a better-integrated Elementor experience, and an AI chatbot (Pro). Echo KB’s five-level hierarchy is more powerful for complex documentation. BetterDocs’ free version is more limited than Echo KB’s free version. For organizations prioritizing design flexibility and comprehensive free features, Echo KB excels. For organizations prioritizing AI-powered documentation assistance and Elementor integration, BetterDocs Pro is the better choice.
Can Echo Knowledge Base articles be private (accessible only to logged-in users)?
Article access control requires Echo KB’s Access Manager add-on. With the add-on: configure individual articles, categories, or the entire knowledge base as restricted to specific user roles or membership levels. Visitors without access see a login prompt or access-denied message rather than the article content. For private company intranets, member-exclusive documentation, or tiered support documentation (basic for free users, advanced for paid customers), the Access Manager provides the needed access control.
Can Echo Knowledge Base break after updates?
Yes, that can happen, especially on older sites with many plugins. This usually happens when the plugin, theme, and add-ons are updated out of sequence. In most cases, testing on staging catches the issue before it reaches the live site. From experience, backups and changelog reviews save a lot of cleanup time.
What should I check before installing Echo Knowledge Base?
Start by checking whether another plugin already does the same job. In most cases, overlap is what creates avoidable conflicts and performance issues. A common issue is installing a plugin because it looks convenient without checking the stack first. From experience, a short compatibility review avoids most of the pain later.
