FOP Module Failure

I seem to get this message a lot. How can I get this to load and no longer receive this message?

Could not reload the FOP operator panel server using killall -HUP op_server.pl. Configuration changes may not be reflected in the panel display. If the FOP module was just installed you may have to retart Asterisk with the “amportal restart” command for the FOP server to run.

I am running asterisk 11, PBX Firmware: 4.211.64-4
PBX Service Pack: 1.0.0.0

Thank you for your assistance.
