Premature Update for Sensei 2.0

Updated on April 4, 2019

Some of you may have seen an update prompt earlier this week that invited you to upgrade to Sensei 2.0. Choosing to update had the following consequences:

  • If you were selling courses, those courses would have been made available for free.
  • If you were using any Sensei extensions (with the exception of Content Drip), those extensions would have stopped working.
  • Sensei translations would have broken.

If your site was upgraded to Sensei 2.0, we strongly recommend that you downgrade to 1.12.3 to resolve the above issues. Choosing to remain on Sensei 2.0 means that your site will NOT receive updates for the plugin going forward. You can downgrade to Sensei 1.12.3 by downloading it from, deactivating Sensei 2.0, and installing/activating Sensei 1.12.3.

Why Did This Happen?

On Tuesday, April 2nd, 2019, we deployed a free version of Sensei to Later in the day, we started receiving reports that Sensei wasn’t working correctly after updating to Sensei 2.0.

This was very concerning, as Sensei being deployed to should have had zero impact on our existing users. This is because existing sites with Sensei installed receive their plugin updates from, not, and so should not have had an update prompt displayed in the first place. Yet intercepted Sensei’s plugin update check, detected that a new version was available, and surfaced an update prompt on your site.

What Did We Do About It?

Once we received the first report of someone being asked to upgrade to Sensei 2.0, we contacted the plugin team at Within 30 minutes of our being made aware of the problem, Sensei was removed from, and the update prompt was no longer displayed in the WordPress admin.

For those users who opened support tickets with us, we asked that they downgrade to Sensei 1.12.3.

How Will We Prevent This From Happening Again?

We have had some communication with the plugin team to determine why this happened.

It would seem that used a combination of Sensei’s name and author fields to identify it. This meant that when your site checked in with for plugin updates, compared the name and author fields of the version of Sensei that was installed on your site to the version that it had on its servers, found them to be the same, and pushed out a notice to update.

We were expecting to use the plugin slug for identification purposes. The plugin slug on (woothemes-sensei) was different from the plugin slug on (sensei). Had the slug been used to identify Sensei, this entire incident would have been avoided.

We are currently planning to resubmit Sensei to However, we will be submitting it with a different plugin name – Sensei LMS. This will be enough to ensure that does not identify existing versions of Sensei as something that it is responsible for updating.


Should you have any questions or comments, please feel free to leave them here. If you need help downgrading, please open a Support ticket and our Happiness Engineers will take good care of you.

We sincerely apologize for the inconvenience this has caused some of our users.
