We’re aware of the problem on MDN in which error messages appear in place of code examples (and a few other places). This is due to a bug in the wiki platform software that causes some of its extensions to fail to load when a server restarts. The problem has been diagnosed by the vendor, and we are awaiting a patch to fix it. Sorry for the inconvenience and thanks for your patience!

The year 2012 is off to a great start for the MDN documentation and its community. This past weekend, a bunch of community members gathered virtually for a documentation sprint to write, update, and translate docs. But already in the preceding weeks, a great deal of work had already been accomplished. This post is a recap of those efforts.
