Java Certificates and the Learning Management system
Some users may notice that their plugins in the Learning Management System (LMS) are not working because they have expired. Some tools and items in Blackboard use a Java plugin known as the Java Runtime Environment. These elements include the wiki and blog tools, the Grade Center, the upload files drag and drop function, and the MyGrades tool amongst others.
About the Java Certificate Errors
Issues with these items can often be resolved by clearing your computer's Java cache. Clearing the Java Plug-in cache forces the browser to load the latest versions of web pages and plugins. We would also advise you to clear your browser cache
Once I do this, will all java errors disappear?
