Window (PC) users reporting issues with things in Canvas that are powered by Javascript–such as Conversations inbox, Discussions and File pages–may be experiencing these problems because of third-party software unrelated to Canvas called Sendori. Removing this third-party software may resolve the issue.

Sendori causes issues with the following tools and features in Canvas: 

  • Conversations Inbox: Messages in user's Inbox do not appear
  • Discussions: Replies to discussion posts do not load
  • Files page: List of files does not load

Sendori’s developers claim that it improves browsing performance for users’ favorite websites. Canvas software engineers found that:

  • A lot of users seem to have had Sendori installed on their machines recently
  • None of the users remember choosing to install Sendori
  • Sendori can interfere with Canvas

If you have Sendori installed on your computer, follow the steps below to remove it:

  1. Click on Start then type Programs and Features into the Search box that appears.
  2. Click on Programs and Features when it appears in the list.
  3. Wait until the list of programs finishes loading and look for Sendori in the list.
  4. Click on Sendori, then click Uninstall near the top of the window.
  5. Follow the prompts on the uninstaller until you get a survey page.
  6. Close the survey page without responding and allow the uninstaller to reboot your computer.
  7. You may also need to update Java and Adobe Flash Player after you have uninstalled Sendori.
