As of February 10th, 2010, jQuery has disabled two popular features, the UI downloader and the Theme Builder. Users visiting those pages on the web site are redirected to a page explaining the decision.

We are aware of the problems with the Download Builder and ThemeRoller and we apologize for any inconvenience this has caused. We have disabled those components on our web site until the problems with these components can be resolved.

While the problems are being worked out, users are being offered two jQuery UI zip files:

• Development bundle, which contains all of the jQuery UI plugins as well as the base theme
• Themes package, which includes all 21 pre-built themes.
