[xwiki-users] XWiki Web Widgets do not display

Our XWiki web site is broken. The symptom is that many buttons, drop-downs, text boxes do not display. We can display the main content web pages and links to other pages work. The trouble comes when we try to administer the web site. For instance, we cannot add a user to a group because the text entry boxes and the "Add" button do not display when the group edit page is displayed. Example GETS that do not work are in the form of http://gallica.ranchsystems.com:8080/xwiki/bin/cancel/XWiki/XWikiPreference… http://gallica.ranchsystems.com:8080/xwiki/bin/lock/XWiki/XWikiPreferences&… These GETS result in the [HTTP/1.1 204 No Content 169ms] error. We welcome all suggestions and advice on the matter.
