Files not being applied to configs

When I click apply on the interface it does not save to the .conf files.

I have checked amportal chown
and retrieve.conf and everything seems fine.

Any ideas whats happening?
I am running freepbx 2.10

How did you install? Did you use a FreePBX distro or install by hand?

installed by hand.
noticed this happened after the latest update of the core module.

Reverted back and fixed the issue. maybe its a bug?
