Could not Start FOP server with AsteriskNOW 1.5

Dear all,

I really appreciate your help on fixing the below two issues:

Issue 1
I could not start FOP Server, I got the following messages:

Message from FreePBX
Could not reload the FOP operator panel server using the bounce_op.sh script. Configuration changes may not be reflected in the panel display.

(freepbx.reload_fop)

Message from the asterisk server
STARTING FOP SERVER
bash: line 0: cd: /var/www/html/panel: Permission denied
usage: kill [ -s signal | -p ] [ -a ] pid …
kill -l [ signal ]


The FOP’s server (op_server.pl) could not start!
Please correct this problem

I got also the following message from the FreePBX:
The following commands failed with the listed error

I appreciate very much if you could help me how to fix these issues.

Thanks and best regards.
