Many of the UI features in TechDoc require JavaScript to be enabled. The action gear, calendar pop ups, and compose email are just some of the features that will not work without JavaScript.
The most difficult issue is that enabling JavaScript varies by type of browser and even by version of the browser. A very helpful web site for enabling JavaScript on most of the popular browsers can be found at https://www.enable-javascript.com/.
If you have a help desk or support organization that you normally call for assistance, you should consider contacting them first to find the recommended way to enable JavaScript for your TechDoc web site.
