Note: this article helps with trouble shooting issues of LTI integrations that have already been successfully installed. The article is NOT directed at admins installing the integration of Grasple with their LMS. If you encounter difficulties during the installation, please reach out to support@grasple.com.

What happens if my settings are incorrect?

When Grasple is loaded within your Learning Management System (e.g. Brightspace, Canvas, Moodle, Blackboard, etc.), your browser should allow third-party-cookies for grasple.com and allow Javascript to be run.

If you don't have the correct settings, launching Grasple within your LMS will not work. This can result in one of the following errors:

  1. Grey screen with "app.grasple.com refused to connect"

  2. Error screen explaining Javascript should be enabled.
