Hi,
I am working on 'Build a Community with Knowledge and Chat' trail and inside 'Enable and Configure Lightning Knowledge' module, I am not able to enable Lightning Knowledge as I cannot see this option in my developer org.

Because of this, I am not able to complete this module. Please help!

Thanks!

Best regards

When I click on 'Lightning Experience' link in Salesforce to enable Lightning in my org, it is showing an error message - "Exception thrown and not caught". Why is this happening? Can someone help on this please?

In 'Creating Validation Rules' challenge, MailingPostalCode and ShippingPostalCode fields are not available in Contacts and Accounts respectively.
