When clicking the Appeon Debugger button on the PowerServer Toolkit toolbar, the "Script Debugger Disabled" error occurs.
Cause: Appeon Debugger needs to use Microsoft script debugger. However, although Microsoft script debugger is available to use, script debugging is disabled in Internet Explorer.
Solution: Enable script debugging in Internet Explorer: Go to Internet Options > Advanced in Internet Explorer, de-select the option under Browsing: "Disable script debugging".
