Login/blog problems

Hi,
Since yesterday my blog stop working, showing just a page without a theme and in the middle the message you get when you search and doesn’t find anything.
But I noticed that the title is not my blog name, but another blog. Also when I try to login into my blog I am being redirected to another blog ( https://www.cfalzone.com/blog) to login there.
My blog is installed here https://www.tomitzel.com/index.php
Please help.
