IntenseDebate Comments


IntenseDebate Comments enhance and encourage conversation on your blog or website. Custom integration with your WordPress admin panel makes moderation a piece of cake. Comment threading, reply-by-email, user accounts and reputations, comment voting, along with Twitter and friendfeed integrations enrich your readers’ experience and make more of the internet aware of your blog and comments which drives traffic to you!

Full comment and account data sync between Intense Debate and WordPress ensures that you will always have your comments stored locally on your own server.

Note: IntenseDebate is currently being maintained, but not actively developed.


  • An example of the comment system itself. Notice all the extra goodies like user profile information, reputation, threaded comments, comment voting, RSS feeds for everything, and more!
  • This is the enhanced moderation screen. Note the extra information about the commenter (same drop down menu for each user from the previous screenshot is available here).
  • The settings page for the IntenseDebate plugin. There are many ways to customize IntenseDebate to do just as much as you want it to.
  • First step in the registration process – syncing up your IntenseDebate account with your WordPress blog.
  • Second step of the registration process – the import to convert all your existing comments into IntenseDebate goodness.
  • Final step of the registration process – a few helpful links to get you started getting the most out of your new IntenseDebate comment system.


Note: As is the case when installing any new plugin, it’s always a good idea to backup your blog data before installing.

  1. After downloading the IntenseDebate plugin, unpack and upload the file to the wp-content/plugins folder on your blog. Make sure to leave the directory structure of the archive intact so that all of the IntenseDebate files are located in ‘wp-content/plugins/intensedebate/’
  2. You will need to activate the IntenseDebate plugin in order to see your new comment system. Go to the Plugins tab and find IntenseDebate Comments in the list and click Activate.
  3. After activating proceed to the plugin settings page (under Settings > IntenseDebate) to configure your plugin. Don’t forget to visit your account at for additional customization options.


Having Connection Issues During Install?

In order for our plugin to work properly, our servers need to be able to get in contact with yours. Some common causes for communication errors:

  1. You’re attempting to install IntenseDebate on a local development server – your site must be online on the “public” internet
  2. Your site is password protected (.htaccess or similar)
  3. Your server is behind a firewall or
  4. A caching plugin might be configured incorrectly

For further assistance, please contact IntenseDebate support at

What is data synchronization?

Comments made in IntenseDebate are automatically backed-up to your WordPress comment system, while your existing WordPress comments are automatically imported into IntenseDebate. You always have all of your comments so uninstalling is a one-click process if you change your mind. Syncing your accounts enables auto-login so logging into WordPress automatically logs you into IntenseDebate. Profile sync also means that comments you make are synchronized to both profiles so you maintain ownership of your profile.

What about SEO?

IntenseDebate outputs the standard WordPress comments enabling your comments to still be indexed by search engines that ignore JavaScript, while ensuring that visitors surfing with JavaScript disabled will be able to interact with comments made in IntenseDebate. Readers with JS disabled can comment in the original WP system and those comments will be imported into IntenseDebate.

How do I sync my accounts?

After installing and activating the IntenseDebate plugin you will need to update your account settings in your Plugin Settings page and either create an IntenseDebate account or login to your IntenseDebate account. Your data synchronization and comment import will start as soon as you have successfully logged in.

Please Note:
Your comments may take several hours to import. The time of your import is dependent on how many other import requests we are receiving in addition to how many comments are currently being imported.

Sounded like a good plugin but it does not connect with your wordpress site after adding the plugin. When trying to login it will always say login failed. I even clicked the create new account and tried and it still failed.

the plugin was successfuly installed. But then I couldn’t enter the comment section. I registered, the registration email went to spam folder 🙂 and connect my WP installation with their API, ok now I can go to comment section, but it then still requires me to connect with their API. After connecting for the second time, an error page showed up saying “Connection refused”.

My honest opinion, IntenseDebate was something awesome in the start, but sadly Automattic gave up on it, and with every month IntenseDebate is becoming something of the past. Now, there is no way to contact the support team, the development is abandoned, and the number of bugs is growing. I recently checked my website’s apache error log: GAZILLIONS of serious errors caused by incorrect SQL behaviour on the intensedebate end. This was terrible. Time to give up on it, adieu, this is a pity.

I am so sorry, but i will not let you generate traffic using my site and redirecting my users to your site! this system is for small and trial sites that doesn’t care about their name or reputation, not for sites that cares who visits them, i looked everywhere for an option that lets me disable the ‘view intense database profile’ and it was nowhere to be found! i think it’s really unprofessional to have that, i’m sorry but you don’t deserve more than one star for this move. Uninstalled and forgotten.
