Unable to see the top navigation menu

If you're unable to see the top navigation menu this indicates that your web browser has font settings that are overwriting the website's font size.  Increasing the font size will cause the top navigation menu to drop to the line below and therefore appear invisible, due to the white colour text on the white background.

To resolve, please review your web browser's settings.  Please look for the content / font settings and remove any settings that are in place to set a minimum font size.
