Hi All, Had an issue this morning thought to share out the fix if any one else comes across this. Server is installed on Windows 7 Machine, and testing on local server too. Not sure if this problem will still happen remotely. I was trying to login extension web portal http://localhost:5000 and was getting access denied from the web server, 3CX web server not IIS. Seemed like i needed to take ownership of folder located C:\ProgramData\3CX\Data\Http\Interface There was a padlock showing, so needed give rights to one of the folders in there. Sorry i can't remmeber the exact folder now, But it does show in your web browser when you get the access denied message.
