exo web site doesn't use extension template anymore (and not working)

Hello,

When we want add new extension page on http://extensions.xwiki.org web site, blank page is open instead the nice extension form.
e.g., URL is http://extensions.xwiki.org/xwiki/bin/edit/Extension/test?template=&parent=Extension.WebHome&title=test
template parameter missing and the new page doesn't contains ExtensionCode.ExtensionClass object.

Of course it is possible to add manually missing objects...
