Signing in to the backpack and connecting via the API will take different code paths, so being able to sign in to the website doesn't indicate the problem is with Moodle. The error you showed is definitely part of Persona's code, and the fact that there are other reported errors with the same message make me strongly suspect it is a persona issue.

I'm not able to reproduce the same issue on my Moodle Cloud account (though I don't have access to IE to test).

So at this stage I think my advice of contacting Mozilla is still the best course of action. Any other information you can provide may help though, for example:

• Exact version of moodle, and server details such as database, server type
• Whether the issue happens for you in other browsers
• Debugging information on network activity during the connection attempt. This will require opening the developer tools and looking for errors on the console and finding and exporting information about requests. I'm not familiar with how to do that in IE so can't really advise further.

Tom,

That particular error looks like a problem with Mozilla Persona (the sign in system for accessing badges from the Mozilla backpack) rather than the code in Moodle.

I've found a couple of reports with similar errors:

https://github.com/mozilla/persona/issues/2009

https://github.com/mozilla/django-browserid/issues/286

You might want to report to the persona team here:

https://github.com/mozilla/persona/issues

I don't think this is related to the recent problems in this thread.

The fix has been released as part of Moodle 2.8.9 and Moodle 2.9.3.

As mentioned above, when testing the fix some more locations that needed to be changed were found - rather than applying a patch I would recommend upgrading to one of the versions above to ensure you have the full fix.

If that's not it (you are already running on 2.8.9 or 2.9.3 but still experiencing problems) can you let us know?

See my latest comment on the bug here. It seems there are some more references - searching the code for BADGE_BACKPACKURL is the best way to find them.

We'll be updating the proposed patch to try to fix all references.

Simon

Ah thank you, we missed that second reference and searching the code for BADGE_BACKPACKURL shows even more - there are 3 references in badges/backpack_form.php and another in lib/badgeslib.php.

It seems like the fix for this might be a bit bigger than we thought...
