Keep in mind that the Disqus WordPress (WP) plugin is designed to replace your WP comment system wherever it is referenced within your templates. Any actions such as closing comments or removing references to the comment template within WP could result in Disqus not displaying properly.

Troubleshooting steps

First, you'd want to ensure that comments are enabled on your posts.

  1. Check that "Allow comments" is checked on all posts you expect Disqus to display. You can verify this by going to Quick Edit on your either of your posts.

  2. See if your Wordpress discussions are not closed, as that will also prevent Disqus from loading. You can do this by going to the discussions tab in your WP admin.

Most WordPress irregularities are caused by theme or plugin conflicts. To test, we'd recommend the following:

  1. Reverting to a default WordPress theme

  2. Disabling all plugins

Common conflicting themes/plugins:

Possible conflicting themes/plugins:

Additional conflicts could occur with any plugins that shorten links or optimize/accelerate pages, as these can edit or confine the scripts needed for Disqus to run.

If none of the above conflicts are causing the issue, it may be a conflict in your browser, please see Browser plugin/extension conflicts for more information.

WordPress F.A.Q.

Can Disqus be used on

Using Disqus on a site requires a Business plan which supports third-party plugins like Disqus. By contrast, a site set up using will be able to use the Disqus plugin without the Business plan.

Is Disqus free to use on my site?

Yes! Disqus is free to use. We also provide subscription plans for larger, commercial sites that want access to more powerful moderation and audience tools and customization.

How do I customize the look-and-feel of Disqus?

Disqus automatically checks your site's font and background color and adapts to either a light or dark color scheme, along with a serif or sans-serif font. If these are detected incorrectly, you can override them in your Settings.

Will I lose comments if I deactivate Disqus?

The Disqus for WordPress plugin supports syncing comments back to your WordPress database. These comments will be available in WordPress should Disqus be deactivated or removed from your site. You can also export your comments from Disqus at any time.

Can I import my existing WordPress comments into Disqus?

Yes, you can import your existing WordPress comments into Disqus during installation.

How do I set up Single Sign-On (SSO)?

SSO allows users in your database to comment without requiring them to register with Disqus. Access to SSO is currently available as an add-on for users with a Business subscription. Also check out our guide for setting up SSO on WordPress.

How can I install an older version of the plugin?

Do install an older version (before the major 3.0+ update), go to to download version 2.6. For more information on how to install, see WordPress' Managing Plugins. Use this version only if you have trouble with the current plugin.
