How to Fix a Java Plug-In Error

Many websites use Java to allow users to interact with features of the site. This can include buttons, graphics, games and much more. Many developers use Java, and their software communicates directly with your Java plug-in. Unfortunately, this means there are countless possible plug-in errors. Fortunately, third-party software that you have must use the official Java plug-in that is installed in your browser. In the event that a Java-related plug-in error occurs, you can simply reset Internet Explorer back to its default state and then reinstall an updated copy of Java.
