(This sounds exactly like bug 50424, but that was marked fixed on 2013-07-15 with "deployed within the hour".) I had made source edits to a mediawiki.org page over https. Looking at it 30+ minutes later I wanted to make one more quick edit, so I clicked [Edit]. VE worked fine, Save dialog, [Review your changes] worked, but the final [Save page] drew blue bars before doing nothing. Firebug's network console showed the API requst visualeditoredit with basetimestamp 20130723212405 format json minor 1 oldid 745108 page Manual:How_to_debug starttimestamp 20130723232059 was failing with {"servedby":"mw1139","error":{"code":"badtoken","info":"Invalid token"}} I had a similar occurrence a few days ago where the API reported badtoken. I can't remember the specifics of that, but I assumed it was my mistake because I was using multiple accounts on different wikis. This time I wasn't doing anything special. Connecting to https://www.mediawiki.org/wiki/Special:Version in another tab shows me as still logged in. Maybe there are two bugs here: VE's inability to recover from this, and the lack of a "VE had an internal error" with suggestion as to how to what to do (e.g. copy the right-hand column of [Review changes]. Regarding the former, when I've lost state with source editing I usually find [Show preview] brings it back, maybe VE can implement something like this internally.
When the API responds with badtoken, VE *should* refetch the token and try again. I'm fairly sure that was implemented, but not 100% sure.
(In reply to comment #1) FWIW when I investigated this by clicking the final [Save page] again, I only saw the one visualeditoredit API request in Firebug's Network tab.
en.wp editor Rpyle731 has just reported an occurrence of this: "While putting in stub templates in article "[[Zhang Shi (prince)]]" using the visual editor, when trying to save I got the text "Error loading data from server. Unsuccessful request: Invalid token.""
I had the same message with the following scenario: Edit an article, not logged in. Then, log in from another tab. Trying to save the article from the first tab, I get the same error message.
This was fixed in Gerrit change #76859 which was merged yesterday and will go out today.
