If this only happens on that one page, try turning off script debugging and see if that helps. If not, you can always turn it back on.
Open Internet Explorer> Click the Tools button> Click Internet Options> Click the Advanced tab> Put a check mark next to Disable script debugging (Internet Explorer) and Disable script debugging (Other)> Untick Display a notification about every script error check box> OK.
Navigate to that page and see if the message is gone. It is almost 100% that the problem lies within that page, and not your PC. But turning off script debugging would prevent the error appearing. This is unlikely to cause you any problems as script errors are rare, and if web pages display normally anyway, it is not a concern. If this doesn't help, I'd recheck/uncheck the above and go back to where you were. A Guy
