Help using Kleo theme

I purchased a Kleo WordPress theme.

Please, i need help for 3 things:

1- I can’t upload the cover image for profile
2- I would like my users activate their accounts automatically without sending mail
3- I don’t want display usernames on the profile

Hello @DavidBony

Hoping it helps,
All the best!
