Cannot access website after installing multilingual plugin Polylang

Hi,

I have installed the Polylang plugin for multilanguage and, after replacing the Italian homepage with the English homepage in the Theme Settings, the website broke and I cannot access the admin panel anymore.

It keeps on redirecting to another URL, even if I deactivated the plugin from the File Manager.

This is the redirect it makes: https://adv.studiocampaner.ro/en/homepage/wp-login.php

Thank you!
