I have been using SO for a few hours this evening and all of a sudden, the edit buttons and preview disappeared. I am using Chrome and OS X 10.7. I just cleared my cache, but the buttons are still gone. Did I do something I am not aware of?
prepareEditor call that sets up the editor has a dangling
, in it, or (even worse) a double
,, if the variable to immediately show you Markdown help is set to true. Most likely explanation is that someone inadvertently introduced an extra comma when the
discardSelector option was added.
All users who access the site using IE are impacted since it considers both conditions syntax errors, and anyone using a non-IE browser will be impacted by the second case.
I've just encountered another setup that can lead to this problem.
I'm using the HTTPS Everywhere extension for Firefox. This means that Stackoverflow is loaded using https. The Google API site appears to be loaded via http.
As a result, Firefox sees the Stackoverflow page as 'mixed content' (secure and insecure elements on the same page), and blocks the insecure elements by default. Firefox indicates that is has blocked mixed content via an icon in the URL bar, but does not provide details on which content it has blocked.
Allowing the insecure elements to load resolves the issue.
