This question already has an answer here:
I tried to suggest an edit on this question to retag it. I clicked the edit button, added my tags, and hit submit to get... this strange error.
This didn't make much sense to me. "I know it would have to be," I thought. "That's why I'm here, right? All my edits are only suggested edits at this point." I hit Save Edits again to receive the same error. I had no idea what was going on, why I was getting an error, and what it was trying to tell me.
It was only once I went back to the question that I found out what was going on: someone else had suggested an edit on this question. I suppose that's what the error was about.
This error doesn't make much sense. Can its wording be changed?
