Good afternoon, I have a problem with a customer FOP2 installed.
The system always worked, now changed the name of a button and restarted the service, after it began to appear the message
"Validation problem. Please contact your provider."

I tried using the command ./fop2_server --test and returned:

[root@asterisk fop2]# ./fop2_server --test
Flash Operator Panel 2 - White Label Version.
Flash Operator Panel 2 - White Label License (5)
Connection to manager OK!
[root@asterisk fop2]#

Can you help me?
