Description Tilman Bayer 2013-07-20 19:42:24 UTC 
After clicking the "Save page" button in the "Save your changes" dialog, the spinner (progress bar) appears for a few seconds, then vanishes again. The "Save your changes" dialog remains open and the edit is not saved. 

Here is the output of the JavaScript Console in Chromium:

The error is reproducible (with this exact console output) even when I make further edits to the article content or change the edit summary and then go back to the "Save your changes" dialog: I can't save seem to save my edit at all. Haven't yet seen this occur in other articles, though (this was an enwiki article).

Which article did this occur on?
Comment 2 James Forrester 2014-03-20 22:51:50 UTC 
No reproduction steps; likely caused by an old issue in alien content blocks, fixed ages ago.
