I did before, however i just made a backup, go ahead.
I tested it with the parent theme yesterday, yes it works. But i tested it too with a child theme with an empty functions.php and a style.css with only the parent theme style inclusion and it still does not work.
This make me think that the problem is that Dante miss loading some files when a child theme is active.
The server is online from 8am to 8pm from Monday to Friday, this is why you found it down.
You can go ahead.
Thank you!
