I was trying to edit a post which had a jsfiddle link. The whole content was not just the link, but I believe there are other posts (like this, for example) that address this. Anyway, when I hit the Save Edits button, I got this error message -
What I don't understand is, if this was a valid error, why was this error message not shown to the OP when he/she asked the question in the first place, thus providing for a more quality question in the first place? (I assumed it was not shown, because if it did, this post wouldn't have been in this shape.) Is it a bug, or could the OP have by-passed this error message (i.e. if it could be done - the OP seems to be a new user)?
