Am receiving errors on every page

For example, on this page, the error I get is:

I don’t know how to code in PHP, but in ASP the equivalent would be that an object has been referenced which has not been initialized. How that translates into PHP, I don’t know.

I am using IE8 (but had the same problems with IE7) on Windows XP Professional Edition with the lastest service pack and all critical updates installed.

Just called up pages on this board using Chrome, Firefox, and IE8.

Did not see this error message anywhere.

This used to happen to me way back in IE5 or 6. I discovered that there was a setting in Internet Options which would turn off these trivial JScript error notifications. The default setting should be a small triangle at the bottom corner of the screen which you can click if you want details of any JScript errors on the page you’re visiting. These errors usually have no impact at all on the way the page displays.

I’ve used FF now for years so I can’t recall which IE option you need to change but it should be quite easy to find.

Just checked my IE7, I’m assuming it will be the same in IE8.

Go to Internet Options, either by right-clicking the icon and choosing Properties, or if IE is running, from the menu.

Click the Advanced tab, scroll down and under the Browsing section you’ll see ‘Display a notification about every script error’. Make sure that box is unchecked. You can also check ‘Disable script debugging (Internet Explorer)’ if you wish debugging turned off completely. (It’s really only of use to webmasters).

These are usually the default settings anyway.

Just noticed that the error appears only when I have InPrivate Filtering turned on.
