View pending and/or discard configuration changes

I have the “Apply Configuration Changes” button displaying and I don’t know what change is pending.

Is there a way to see what is in that list of changes, and possibly discard them? Clicking Cancel on the Apply does not discard changes.

PS: If it’s not in the interface, it should be. I’m using FreePBX 2.7.

I have the same problem. CentOS 5.4 FreePBX The button displays constantly, but when we click it, and continue with the process, it sits there for about 30-45 seconds and finally errors out and says “Did nto receive valid response from server”. It also drops any calls that may be coming in or in progress when we click it. The button does not go away even after a server reboot.
