Test a Web page from another user account, another browser, and another computer
If the problem only occurs when you view one or two Web pages, view the pages from another user account, from another browser, or from another computer to determine whether the problem persists. If the script error persists, there may be a problem with the way the Web page is written. Contact the Web site administrator or content developer to inform them of the problem with the Web page. If the script error does not occur when you use the Web page from another user account, the problem may be caused by files or settings for your user profile. If the script error does not occur when you use the Web page from another browser or another computer, then continue troubleshooting.
