All links redirect to home page

Good morning everyone!

I have a problem since this morning, all the links redirect to the home page.
I tried to disable all plugins but it didn’t work.
By changing the . htacces file to .htacces.0 I managed to access wp-admin which until redirected to the home page. However all admin links like theme or plugins redirect to the home page. So I am blocked.
I noticed that all links even a URL that does not exist like mydomain/randomtext redirect to the home page
Do you have a solution, please?

The page I need help with: [log in to see the link]
