Hi. I'm not sure if this is the place to post my question. If it isn't, please 
accept my apology and remove the post. I'm a new user and have been trying 
unsuccessfully to get the OpenFPC web GUI to work. I have reinstalled a couple 
time and run into the same issue. Please assist if possible. Thanks very much 
in advance.

I followed the install instruction closely. Was able to extract the pcap using 
CLI:
openfpc-client --dst-addr=[ipaddress] -w /var/log/test --last 600

The status shows

I had a similar issue and the fix was to copy /usr/sbin/mergecap over to 
/usr/bin.  Give that a shot.

I'm experiencing this same issue.   Coping mergecap fixed the problem until 
reboot now the issue is back.

I solved this issue by disabling selinux on redhat 6.5
