cPanel is so wonderful that it fixes most of it's broken stuff if you run "
/scripts/upcp --force", the magical command from SSH as root.. if you've messed up with the permissions or other things, we've necessary backups of your data, that can be restored if needed..
Also, to be on a safer part, it's always advised to contact support prior to making any major changes to the control panel or the VPS. If, in case, it's broken & you're unable to get your hands over it, our well skilled
VPS Support Dept, would willingly get it sorted out for you :dancing: Good luck.. ;)
