Also today around 4pm, when wikipedias got switched to 1.23wmf1, the
mobile site experienced the classic debug=true issue - a JavaScript
exception was being thrown due to what I think was some old code being
loaded (when debug=true was appended this error didn't occur so I
suspect some caching issues). Reedy seems to have fixed it with lots
of file touching (thanks Reedy)! Greg, what can we do to avoid this
happening again?
