Moesia Template is missing

Hi, I am getting an blank page when accessing my site and the following message:

Template is missing. Standalone themes need to have a index.php template file. Child themes need to have a Template header in the style.css stylesheet.

Please help

Hello @eliemo,

Do you use a child theme?

Kind Regards, Roman.

no i don’t, and never did, and the site was working ok

Okay Elie,

Can you please try to reinstall the theme?
You can learn how to do it here:

But please create a full site backup first.
