Currently https://fr.wikipedia.org/wiki/Wikip%C3%A9dia:Forum_des_nouveaux/Flow leads to the message: Internal error [1e3e5c74] 2014-09-27 01:10:46: Fatal exception of type MWException Webconsole says: "[FLOW] " "Will not instantiate: no $container.length" Arguments { 0: Object, 2 more… } ---- Possibly separate, or the same: Clicking the history tab gives: [0e33f8fa] 2014-09-27 01:12:45: Fatal exception of type MWException but no extra details in webconsole

Also at https://en.wikipedia.org/wiki/Wikipedia_talk:Flow/Developer_test_page
The pages have been temporarily fixed by Ebernhardson, so am lowering severity. He is unsure what caused it, but purged the problem manually. See https://trello.com/c/AoDOJxUq/ for making that purge script available via onwiki action.

Also happening on mw:Talk:Search exception.log backtrace (below, key is [6ba6245c]) is similar for #0-#3, then diverges. I think I'm viewing a different way. If I try to view the post from "Did not load root post <UUID>" from the exception, https://www.mediawiki.org/wiki/Topic:S1b3m6774w8qpf8t , I get a worse exception with no page chrome at all, just [7db57483] 2014-09-28 22:13:56: Fatal exception of type MWException. That log below too. Purging the problem post with ErikB's script didn't help, but purging Talk:Search fixed both the topic and Flow board.

Getting this when trying to view a post on [[mw:Talk:Search]]. This is the link I got in the messages: https://www.mediawiki.org/w/index.php?title=Topic:S1b3m6774w8qpf8t&fromnotif=1#flow-post-s3ermfxsleu9goor and it blows up with this error.
