I stumbled upon the exact same error message when trying to ask a question on a meta site.
After taking a look here to see if that happened to anyone else, I was amazed to read the kind of answers
Aamir Adnan received from the majority!
The question I asked was perfectly clear, in a perfectly good (or at least very understandable ) English.
Nothing on the How to ask a question page (for which the link is not shown when the error appears or probably hidden somewhere) helped solve the problem.
Thinking the post might be too short (2 sentences, that's all I needed to ask a clear question, adding more would have made me look retarded) I simply added a lot of rubbish and it finally got accepted. (talk about quality standards...)
Of course I edited afterwards and removed the gibberish. Since it got edited very quickly after the submit, no traces were left of the original post.
So I repeat
Aamir Adnan's question: What are these quality standards you are referring to?
When the title is too short, I get a clear message telling me to put more than 15 characters. Why doesn't it work for the body of the question?
Additionally some of the comments here are extremely rude and very close to racism. One of them native speaker who comments on "good English" uses an even poorer language than the OP.
