Hi there!
I hope you’re doing great. Thanks in avance for the great help this forum is providing, it helped me a lot already!
My website https://wercury.ch/ just started doing something pretty strange a few days ago - when I try to go to any page from the homepage, only the header and footer seem to be shown, and I am not able to access to the backend via /wp-admin or /wp-login URLs at all!
I still have access through the FTP manager, but I’m quite at loss about where the error could be from. I tried re-installing a fresh version of WordPress in /wp-includes/ but it did not change anything. I think it might come from an issue with the content of the theme not showing, but I am not tech-savvy enough to work this out.

If anyone could help on this, thanks a billion!
