404 error on my entire site

Hello, dionicordova, are you able to access your site through FTP? If so, are you able to check your file directory is similar to described in https://www.malcare.com/blog/beginners-guide-to-understanding-the-structure-of-a-wordpress-site/.

Additionally, do you have PHPMyAdmin access? If so, I would also suggest reviewing the database and seeing if it’s like https://wp-staging.com/docs/the-wordpress-database-structure/.

Looks like your site has been hacked. Best to contact your Hoster for advice ASAP.

I say that because the ‘index.php’ file (which is the first page to load) has been renamed to ‘index.php.bak’ by somebody or something.
