Best answer as chosen by user 2rvers: Answer to script error
This usually occurs when there is a problem with the web designers code. You cannot fix this yourself but you can turn off the error message. Open internet properties on your pc. Click on the advanced tab. Go to the browsing section and place a check mark next to Disable script debugging (Internet Explorer), Disable script debugging (Other), and Display a notification about every script error. This should solve your problem with the script error warning.
