Hi.
I have uploaded 222 subtitles today. Half in spanish, half in English. All for Babylon 5 episodes.
All the spanish ones were "recognized" as English.
They all had .es.srt as the name suffix.
I have tried editing them but after a dozen or so I got "Hacking Attempt!" warnings. So I've stopped.
It seems the autodetect language is not working properly upon upload (it works in the "Correct Subtitle" page) and that hacking attempts are detected even in subtitle edition pages.
