tinymce is not defined

[Former user]

I just installed this plugin and when I try to add the gadget to a dashboard I get the "tinymce is not defined" error.

Once I click "ok" on the error message the configuration for the gadget loads but it will not let me save it.

Thanks for reporting, is it working now?
I tried installing on a new site and it seems to work for me.

If not, can you let me know if there are any console errors pls?

Oh, thanks for the console logs. It looks like you might have third-party cookies disabled in the browser?

This is a company managed policy and I’m not allowed to enable third-party cookies. I would need to request an exception be added for this. What domain would need to be added to the exception list? https://rich-text-gadget.us-west-2.prod.public.atl-paas.net

Yes, that’s the right domain.
I had a look, but the underlying library (tinymce) is dependant on cookies, and can’t be configured to work without them - sorry!

Allowing third-party cookies resolved the issue. Thanks!
