Cache clearing fails after 1.11.7 upgrade+discussion
thanks for the bug report!
You're obviously right that there's a bug, but the good news is that it does appear to happen after the cache gets cleared. It's just an error displaying the final message (because of new layout handling). I'll patch it quickly, but know that if you get this message your cache has been cleared.
I posted a fix. It was tiny, and we just got out the release yesterday, so I just re-tagged the release. But the latest on master should not have this problem.
(note: for now it will just give the response as simple text. Soon it will go back to the old behavior.)
