After doing a upgrade to FreePBX, the Flash Operator Panel not working.
I have the following error and nothing display when I select the Panel tab, what could this be?

You might want to contact Nicolás Gudiño. He wrote FOP. If you go to
http://www.asternic.org/

There is a chat link in the lower right. He will probably want to know what version of FOP you have.

To find Flash Operator Panel version:

Find where op_server.pl is located:
[email protected]:/ $ find / -name op_server.pl
/usr/src/freepbx/amp_conf/htdocs_panel/op_server.pl
/var/www/html/panel/op_server.pl
/var/www/html/admin/modules/fw_fop/htdocs_panel/op_server.pl

Goto that directory:

[email protected]:/ $ cd /var/www/html/admin/modules/fw_fop/htdocs_panel

And run the command below:

[email protected]:/var/www/html/admin/modules/fw_fop/htdocs_panel $ ./op_server.pl -v

The result will look something like this:

    op_server.pl version 0.30
