1. Remove the text on the Create a website tab that says “ignore” really can just delete whole line 2. Database records for SSL need to be deleted from database when switching from Static to Dynamic (If you make a cert request, switch and switch again it shows the prior request. It should be defaulted again) 3. Instant alias should ignore global dns rules
