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.

What happens if my settings are incorrect?

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.

Grey screen

If you get a grey screen without any buttons or text, Javascript is disabled/blocked (for third-party origins) within your browser and/or extensions. To use Grasple you should allow Javascript to be loaded and run from the domains: grasple.com and ihatestatistics.com (the old domain and name for Grasple).

A login screen or error screen

If this happens, your browser and/or extensions do not allow third-party cookies. When Grasple is loaded within your Learning Management System, Grasple is seen as a third-party.
Allow third-party-cookies to bet set for the domain grasple.com in your browser and or extensions.

WARNING: Safari's default settings do NOT allow for third-party-cookies on all their devices (Macbook, iPad, iPhone). However, they only provide the option to allow third-party-cookies from all sources. Our advise is to use a different browser (Chrome) where you can control the cookies in a more elaborate way. If you want to use Safari for Grasple within your LMS, you have to allow third-party-cookies.

How to configure my browser correctly?


By default Safari on both Macbook and iPhone do not allow third-party-cookies. Change your settings if you want to use Grasple within your LMS while using Safari.


  1. Go to Safari > Preferences
