Notes:

• You must take these steps in each site you have Guest Users enabled. It isn't global across all sites. 
• Guest Users can't attach files when creating a Case.
• The Site Details User Interface section that will allow you to perform this step "Add 'NewCase', or a custom quick action to add Cases, to the 'Selected Quick Actions.'" may be missing. Please log a Salesforce support case requesting to enable required org permission. Please reference Article Number 313406 in your support case. 
• If you are receiving a message, 'Looks like you don’t have access to create a case. Ask your community manager for access', please review the following to resolve: Error 'Looks like you don’t have access to create a case. Ask your community manager for access.' when you create a case from the 'Contact Support Form'.
• The Automated Case User (within Support Settings) must have access to the record type and fields on the global action layout for the case creation under Contact Support Form or Create a Case Form.
