Another case of the same error. Translating w:en:Sack of Wexford to w:pl:User:Halibutt/Oblężenie Wexford. Can't publish.
Topic on Talk:Content translation/Flow
Are there any fixes or ETAs on the HTTP400 error reported here every once in a while? It happened again, this time translating the article on :w:en:Caroline Sturdy Colls to Polish (hopefully to :w:pl:Wikipedysta:Halibutt/Caroline Sturdy Colls). I translated the entire thing, copyedited it, expanded it a little and... Bam, on my way to clicking "Publish" I accidentally clicked on that damn infobox. Which means the entire thing is now greyed-out and when clicking "Publish" I get error 400 ("Error converting HTML to wikitext: docserver-http: HTTP 400"). This is extremely, extremely frustrating.
BTW, at the latest Wikimedia Polska conference I held a workshop on using content translation tool. Fortunately I didn't click on any templates then, or the entire presentation would end badly.
