Do I need iSymphony

This morning I did a module update to my FreePBX system. Now, the asterisk command line (asterisk -rvvvvvvvv) is complaining “Could not write configuration data isymphony/variables.txt. Check your file permissions.”

I am unable to locate a variables.txt file on the distro. So, I cannot check permissions.

So, I thought, well then stop the isymphony server and test if the complaint will stop. Ran service isymphony stop and the complaint continued. (So, I restarted the service.)

What do I do?
