trying to try you out from Google Chrome, by my soup - ramage.soup.io - isn't giving me an login/editing options, and the bookmarklet will only let me post to the demo site try.soup.io

I believe somebody's already had this problem before, but I can't find the right example.

I recently posted a video on my soup through pasting an embedded code, and now my soup stops loading on this post. Also the sidebar has disappeared, so I can't edit anything.

I'm pretty sure the code was broken, but what can I do now to delete/edit this post?

When fetching feed some of the videos disappear in posts. Those videos work ok when checked in feedreader though.

If this is a problem on soup.io side, please take care. If not - is this possible toedit html of the post to insert correct embed code manually?
