Last night we were moving some accounts from one cPanel server to a new server and WHM wasworking fine then. This morning the WHM stoped working. I rebooted the box but the WHM is still down. Does anyone know any reason this would happen or how to find a solution? Thanks.
Just for troubleshooting sake, try "setup" then choose firewall and select "No Firewall". That would potentially eliminate your software firewall as being the culprit asuming you are using the default linux firewall included with a standard OS installation.
I would submit a ticket to CPanel. They're typically very good about returning support tickets for their product in a timely manner.
I would also be interested to know what's in: /.bash_history
Thats the file that holds recent console commands and sometimes reveals things we don't remember doing.
