One of the main reasons this error message appears is because of pop-up blockers. Most of the time, these pop-up blockers prevent some windows from appearing. Usually the windows that are blocked are ads from different types of websites. While blockers are designed for such windows, they can also prevent some of the Java-based scripts from achieving what they are programmed to do. But you can actually give a solution if you don’t want to see this error message over and over again, you can easily go to options and change your pop-up blocker preferences. It is also important that before you get a pop-up blocker, you take some time to read whether it would block scripts like Java.
Another reason Javasciptvoid 0 error appears is the compatibility issue between the browser and the web page you are browsing. If you think you will be a frequent visitor to this site, you can contact the webmaster so they can do something about it.
