Then you'll be able to tweak any script usage and avoid errors associated with too high of a security level.<BR><BR>Edit: Just noticed your pop-up ad filter program. Just disable script debugging.

1] Disable Script debugging If Script debugging is enabled in Internet Explorer 11, you will face the error. So, to face this issue, we need to disable this feature.

First, uninstall and then reinstall the browser. Secondly, if script debugging is enabled, disable it. Third, disable all extensions.

How about just checking the 'Disable script debugging' boxes in Tools, Internet Options, Advanced? That way, you won't see the errors, which most often are problems with the site anyway.
