Restrictions on Browsers

  • You are advised to use the following browsers to access the CSS management console:
    • Google Chrome 36.0 or later
    • Mozilla Firefox 35.0 or later
    • Internet Explorer 9.0 or later

      If you use Internet Explorer 9.0, you may fail to log in to the CSS management console because user Administrator is disabled by default in some Windows systems, such as Windows 7 Ultimate. The Internet Explorer automatically selects a system user for installation. As a result, the Internet Explorer cannot access the management console. Reinstall Internet Explorer 9.0 or later (recommended) or run Internet Explorer 9.0 as user Administrator.

  • You are advised to use the following browsers to access Kibana integrated in CSS:
    • Google Chrome 36.0 or later
    • Mozilla Firefox 35.0 or later
    • Internet Explorer 11.0 or later (Internet Explorer 9 is not supported.)
