SLACKSCRIP setup cPanel for me. I could not login with the root password, even though I could SSL into the box, change ~/.bashrc, then exec bash after adding
export PS1="[\u@\h \W \@]\$"
So, this was a script error. after telling them 4 times the password was the problem, they finally realized, it was a password problem.
