How to report an error in an online training? or a broken quiz?

There is no volunteer-facing technical support, beyond what’s available in these forums. The only other route to technical support is via the council professional staff, who do have the ability to file a support ticket with national.

However, as @DonovanMcNeil noted, this has been raised before, and unless something has changed, this sounds exactly like the prior “errors” that have been reported. It’s a poorly phrased question, with what is, in my opinion, a poorly phrased error message Nevertheless, it’s not viewed as an issue by BSA, based on the prior responses that have come back via the forums, such as here: Unable to take online trainings - #16 by CharleyHamilton.
