If the page you are testing is empty or does not contain any HTML elements, you might receive a Could not recognize any HTML classes in your browser application message. Your configuration might be correct, however, the automated configuration test does not support testing of blank pages or pages that do not contain HTML elements. You can manually verify that your extensions are set properly, open your application, and then record window declarations. If you can record against HTML classes, the extension is configured correctly and you are ready to set up the recovery system using the Basic Workflow bar.
