unexpected T_CLASS errors – site shut down

Try switching to the unedited default Theme (Twenty Seventeen.) for a moment using the WP dashboard to rule out any theme-specific issue (theme functions can interfere like plugins). If you don’t have access to your Dashboard’s Appearance page, use FTP/ SFTP , or your web-host’s cPanel or whatever file management application your host provides (no Dashboard access required). Navigate to /wp-content/themes/ and switch to the default theme by renaming your current theme’s folder by adding “-old” to the end of the folder name. Alternately, you can remove other themes except the default theme (Twenty Sixteen.). That will force your site to use it.

I tried that. Now the main site page doesn’t have an error message but it is blank.

/wp-login.php shows me the login screen but says my username is invalid. It’s not.

/wp-admin displays this message:

I did some digging and found suspicious files. I’ve been hacked.

Sorry to hear that.
