I had a functional FOP2 setup running on FreePBX 2.10. I did the update to 2.11 and the system would not load the Asterisk service. I found a note that said to uninstall FOP2 admin module. http://www.freepbx.org/forum/general-he ... ot-applied - That did not completely fix the issue.

I contacted Schmooze and they found the CEL was an error, we moved the cel_*.so modules out of /usr/lib/asterisk/modules to the home directory. - Now FreePBX seems to work.

Once the server was back up I tried to reinstall the FOP2 Admin module again and the FreePBX server had and error and Asterisk stopped running. I have since uninstalled the service and the server is fine. I have version 2.26 of FOP2
