Problems with Java

  • I recently updated Java (Version 8, Update 121) on my Mac (OS X 10.11.6) But when trying to verify JAVA via the following message appears:

    We are unable to verify if Java is currently installed and enabled in your browser. If you have installed Java and there is an error with the verification, there could be a configuration issue (eg. browser, Java control panel, security settings) or the Java plug-in is blocked by the browser. Try restarting your browser before trying to verify the installation again, and check that the browser allows Java to run.

    I do allow JavaScript on all sites as recommended in the settings (Opera version 43.0.2442.806) as well as browser Java-content in the Java Control Panel.

  • Hello @remilino. The Oracle Java plugin doesn't work with browsers like Opera and Chrome, because the plugin architecture it uses is no longer supported. If you really need to display a Java applet (note that this is not the same as Javascript, and there are very few sites left using Java applets), you'll have to use Safari.

  • Thank you, avl! Do you know if is one of these sites requiring Java?

  • They should tell you if they do ... that is, a site that uses Java should try to see if it is installed (and what version) and display an error message if it's not available.

  • The source code says, that only Javascript is needed (which is enabled in my Opera settings). Maybe I just have a sort of caching issues that cause CSS problems. I made a short screen video to show what I mean: Any idea whats going on here?

  • Same problem here. With version 42 on my notebook the website works. With version 43 on my desktop pc don´t. With Chrome and Firefox the same page works. Only v43 makes problems.
