502 Bad Gateway Error

All of my domains display a 502 Bad Gateway error now. See www.mikespray.com

This happened after I rebuilt the vHosts file using the Rebuild function in CWP (while trying to fix the issue where all domains display the same page)

How can I fix this?

1) Noticed that Apache was not running for some reason

2) Tried to start Apache...Apache still would not run. Something something about a socket/port, already binded...bound...whatever.

3) Rebooted server, everything works now.

Note to self, reboot the server before you wonder why it doesn't work.
