How to change site preview path?

[matteopratelli]

Good evening ,

I've just installed a new theme on my PrestaShop updated to latest version , but I can't display the site preview.

Before to change the theme I was able to see the preview of the default theme, but now now clicking "Preview" I finish on a horrendous default page that says "Welcome to Parallels ."

Same thing on the URL of the site (which for the moment I want to keep offline)

How can I change the path and show the current theme? I have to do it by FTP?

Thanks for your help
