Hi.
Well done !
The demos page are working.
But I have the same problem in production :
With this originals includes (that works fine before) :

1. <link rel="stylesheet" href="http://jquery-ui.googlecode.com/svn/tags/latest/themes/base/jquery-ui.css" type="text/css" media="all" />
2. <script type="text/javascript" src="http://jqueryui.com/js/jquery.js"></script>
3. <script type="text/javascript" src="js/jquery-1.3.2.min.js"></script>
4. <script type="text/javascript" src="js/jquery-ui-1.7.2.custom.min.js"></script>
5. <script type="text/javascript" src="http://jqueryui.com/themeroller/themeswitchertool/"></script>

Or this one :

1. <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script>
2. <script src="http://jquery-ui.googlecode.com/svn/tags/latest/ui/minified/jquery-ui.min.js" type="text/javascript"></script>
3. <script src="http://jquery-ui.googlecode.com/svn/tags/latest/ui/minified/i18n/jquery-ui-i18n.min.js" type="text/javascript"></script>
4. <link rel="stylesheet" href="http://jquery-ui.googlecode.com/svn/tags/latest/themes/base/jquery-ui.css" type="text/css" media="all" />
5. <script type="text/javascript" src="http://jqueryui.com/themeroller/themeswitchertool/"></script>

I obtain the same result :



With an hoover in a theme in the selector i obtain this strange thing (the localhost part indeed) :

1. http://localhost/themeroller/css/parseTheme.css.php?ffDefault=Lucida+Grande,+Lucida+Sans,+Arial,+sans-serif&fwDefault=bold&fsDefault=1.1em&cornerRadius=5px&bgColorHeader=5c9ccc&bgTextureHeader=12_gloss_wave.png&bgImgOpacityHeader=55&borderColorHeader=4297d7&fcHeader=ffffff&iconColorHeader=d8e7f3&bgColorContent=fcfdfd&bgTextureContent=06_inset_hard.png&bgImgOpacityContent=100&borderColorContent=a6c9e2&fcContent=222222&iconColorContent=469bdd&bgColorDefault=dfeffc&bgTextureDefault=02_glass.png&bgImgOpacityDefault=85&borderColorDefault=c5dbec&fcDefault=2e6e9e&iconColorDefault=6da8d5&bgColorHover=d0e5f5&bgTextureHover=02_glass.png&bgImgOpacityHover=75&borderColorHover=79b7e7&fcHover=1d5987&iconColorHover=217bc0&bgColorActive=f5f8f9&bgTextureActive=06_inset_hard.png&bgImgOpacityActive=100&borderColorActive=79b7e7&fcActive=e17009&iconColorActive=f9bd01&bgColorHighlight=fbec88&bgTextureHighlight=01_flat.png&bgImgOpacityHighlight=55&borderColorHighlight=fad42e&fcHighlight=363636&iconColorHighlight=2e83ff&bgColorError=fef1ec&bgTextureError=02_glass.png&bgImgOpacityError=95&borderColorError=cd0a0a&fcError=cd0a0a&iconColorError=cd0a0a&bgColorOverlay=aaaaaa&bgTextureOverlay=01_flat.png&bgImgOpacityOverlay=0&opacityOverlay=30&bgColorShadow=aaaaaa&bgTextureShadow=01_flat.png&bgImgOpacityShadow=0&opacityShadow=30&thicknessShadow=8px&offsetTopShadow=-8px&offsetLeftShadow=-8px&cornerRadiusShadow=8px

Hope that those elements can help.

PS: There is somewhere a download of the themeswitcher widget that we can download and don't be dependant of the infrastructure ?

Thanks.
