VPS Server Root Password Change

I believe it was compromised. I get this message when I try to change the password. Can't use string ("1478369364") as a HASH ref while "strict refs" in use at /usr/local/cpanel/Cpanel/[login to view URL] line 196. at /usr/local/cpanel/Cpanel/[login to view URL] line 196.
