Let's assume you use Internet Explorer when this message appears. Then you go into Tools>Options>Advanced and turn off error messages and error detection in scripts for Internet Explorer (two different checkboxes, in IE9 at least). And if it isn't Internet Explorer, you'll find a checkbox for other programs also.
If that doesn't help, then tell what it is and what page.
