  • Glossary Index Page ID - Here you need to select the page that you would like to use as the Glossary Index Page. If you select -None- terms will still be highlighted in relevant posts/pages, but there won't be a central list of terms (Glossary Index Page). 
    • Generate page for Glossary Index - If you check the checkbox, a new page will be generated automatically. Note: you have to manually remove old pages.
  • Exclude Glossary Term Pages from search - Uncheck this option to remove Glossary Term pages from search results.
  • Glossary Terms Permalink - Enter the name you would like to use for the permalink to the Glossary Terms. By default this is "glossary", however you can update this if you wish. If you use a parent, please, indicate this in path eg. "/path/glossary", otherwise just leave glossary or the name you have chosen. The permalink of the Glossary Index Page will change automatically, but you can also change it manually using the edit link near the Link to the Glossary Index Page above. Note: if you already use this permalink the plugin's behavior may be unpredictable. This option cannot be empty.
Term highlighting

The are several settings that helps you select where to highlight the term. You can choose to disable the highlights on posts or pages, or any other custom page.

Term highlighting settings - Glossary Plugin WordPress
Term highlighting settings
  • Highlight terms on given post types - Select which post types will have highlights/tooltips. Note that you can also control if tooltips appear on specific pages while editing those pages.
  • Only show terms on single posts/pages (not Homepage, authors etc.)? - Select this option if you want to highlight glossary terms only on a single page/post. This is for cases when you don't want terms to be highlighted on your homepage, or author pages and other taxonomy related pages.
  • Highlight first term occurrence only? - Select this option if you want to highlight only the first occurrence of each term on a page/post.
  • Highlight only space separated terms? - Select this option if you want to search only for the terms separated from other words (usually by space).
Performance & Debug

Here you will find settings that may help solving conflicts with themes or other plugins.

Performance & Debug settings - Tooltip Plugin WordPress
Performance & Debug settings
  • Load the scripts in footer? - This setting allows you to load the scripts and CSS styles ay the end of your page, which can speed up the initial loading of the pages, but can create problems. Try unchecking this setting option if:
    • You notice some errors related to the WordPress Glossary plugin in the Chrome Developer Console.
    • The tooltips are not displaying although the terms are correctly highlighted and tooltips are enabled in the settings.
    • Tooltips are styled incorrectly.
  • Only highlight on "main" WP query? - Some themes are using more than one query on each page (eg. for some data manipulation) which results in the terms being parsed only on the first "main" query and not on the one which outputs the data on the screen. This is most often the case in the themes using page builders. Try unchecking this setting option if:
    • Terms are not being highlighted at all (although you're sure the page/post contain the term).
  • Run the function outputting the Glossary Index Page only once - In extremely rare cases the Glossary Index appeared multiple times on the same page. Try checking this setting option if:
    • The Glossary Index is appearing multiple times on the same page
  • Run backlink generating function only once - Select this option if you want to show a backlink to Glossary Index on glossary term page only once.
  • Enable the caching mechanisms - For performance reasons we've developed an internal caching system for the complex queries. However, enabling it can make the plugin unstable.
  • It's advised to only use this option if the Glossary Index Page or a page with lots of terms is extremely low. Try unchecking this setting option if:
    • Newly added terms are not being parsed in your older pages.
  • Clear caches actively - Select this option if you want to actively clear the internal caching mechanisms. Only works if the mechanisms are already disabled, also increases the database usage, so it's best to deactivate after a while (week).
  • Move tooltip contents to footer? - Makes the tooltip content to not be passed directly to JS with the HTML attribute. Try checking this setting option if:
    • The tooltips seem to be breaking your layout. This sometimes happens with the builders or very long term descriptions.
  • Don't use the DOM parser for the contentWarning: Only those very familiar with WordPress development should change this setting. Select this option if you want to parse the content using the simple parser (preg_replace) instead of DOM parser. Try checking this setting option if:
    • You are having compatibility issues
  • Tooltip Parsing PriorityWarning: Only those very familiar with WordPress development should change this setting. Choose in which priority the tooltip will be parsed, compared to other plugins or themes (default value is 20000). Try checking this setting option if:
    • You need to solve compatibility issues with specific themes or plugins.
  • Use a non-minified version of tooltip script - Select this option if you want to use non-minified version of the tooltip.js file. Try checking this setting option if:
    • You are having compatibility issues.
  • Turn on AMP - Select this option if you want to show tooltips in AMP pages. Learn more about it in this guide: Showing Tooltips on AMP Pages (Accelerated Mobile Pages)
