If you receive a Script Error message when surfing with Internet Explorer, try the following.
Clean Up
The first method that you should try is by clearing cache and cookie info from the machine to see if it resolves the issue.
Reset The Browser
Resetting the Internet Explorer browser is one way of solving the Script Error message. Do this only if other free Internet browsers that are installed on that machine is fine or if Internet Explorer is operating normally on other computers located on your network as this will prevent you from eliminating local browser settings when the issue is on the website itself.
