Hi, I need to access the AppExchange for a test on Trailhead but after resetting the password for my Trailhead sandbox it won't accept it. I copied the username from my user page and everything matches. Is there a reason why this would happen?
Thanks

I'm doing the simple lightning components challenge and have hit this problem in my existing trailhead org and a brand new dev org that I've just created:

Challenge not yet complete... here's what's wrong: 
There was an unexpected error while verifying this challenge. Usually this is due to some pre-existing configuration or code in the challenge Org. We recommend using a new Developer Edition (DE) to check this challenge. If you're using a new DE and seeing this error, please post to the developer forums and reference error id: QVWBQHAG

I am having trouble displaying fields on my visualforce page when I add it to the site. I have checked all the public access settings and the field level security, they are both set as they should be. It is like I do not have access to the object itself. When I do <apex:inputField value="ObjectName.Field__c" /> it shows up in the visualforce page but not the site. We are using record types for this object but everything seems to be fine there as well. Does anyone have any expirence with this?

Thanks!
