unable to make changes to any of the existing extensions on V20 Update 2

[dza]

I'm unable to make changes to any of the existing extensions.

For example, if I try to make an extension a system admin or owner, or simply change the first name for an extension, I get redirected to the 3CX talk tab, where I need to choose a friendly name, which I guess is now a mandatory field. But I am unable to save the changes due to this error: "undefined: The input was not valid. delta: The delta field is required."

What exactly is the delta field? Any thoughts?

Just try to put something short in the talk name field. like "talkname" or something else. Without any special signs.

I did that already. I entered a valid name that meets the requirements ( no uppercase, spaces, etc.), but I still get the same error when I hit save.

Than there is something different wrong... Did you reboot the pbx and tried again?

Does this occur also to a newly created extension?

Thanks all. Yes, it was happening on newly created extensions, but after upgrading to the latest version, the issue was resolved.
