I upgraded to version 8.0.10824.716 (Small Business Edition) about one week ago. Today was the first day I've tried to add or edit an extension and every time I click the OK button to apply the changes I get a Windows pop-up stating "An exception occurred EditExtension Error: Object reference not set to an instance of an object." This happens in both the Windows console version of the Management Console and in the web version of the console. I can edit Ring Groups and Queues with no problems. Call origination and termination works fine. I just can't add/edit Extensions. There are no entries in any of the 3CX logs after I click the OK button, and no entries in the Windows Event Logs. I restarted the server running 3CX and the problem persists. Anyone have a suggestion on how to fix this? Thanks.
