Your security settings have blocked an application signed with an expired or not-yet-valid certificate from running
In the case, the error message has come from a content management system, MySource Matrix (by Squiz).

Solution

The issue (an expired or invalid certificate) needs to be resolved by the application developer – you should point them to this article: https://www.java.com/en/download/help/signedjar_dialog.xml
But if you trust the developer you can add it to the exception list. This will allow the application to run.
How to add a website to the Java exception list
- Open the Windows start menu and type ‘Java’ into the search box
- Under ‘Programs’ click on ‘Configure Java’
- The ‘Java Control Panel’ window will open.
- Click on the ‘Security’ tab then on the ‘Edit Site List’ button
- Click on the ‘Add’ button and in the space under ‘Location’ enter the address of the website, for example ‘http://website.com’
- Click ‘OK’
- If your website address uses HTTP (not HTTPS) you will see a warning message – click ‘Continue’
- Click ‘OK’ to close the Java Control Panel.
- Your Java app will now load – you may need to close and restart your browser.
