Check your public_html in File Manager from cpanel; there'll be 2 .htaccess files. One is .htaccess, the other is .htaccess.suspend - try renaming .htaccess to .htaccess.old, and .htaccess.suspend back to .htaccess - this should fix the redirect but you may need to clear cache.
Edit: If this does work you can delete .htaccess.old, I'm only suggesting rename to make sure it -is- working first, cause if it doesn't you may want the file around
