space return error

[Cuong0]

Space return error while editing listing. I can do a space return normally as I was typing in the box, yet it wouldn't appear in the actual displayed text. Now all my text is lumped into one paragraphs which makes it look very hard to read. Anything suggestion on how to fix this problem?

I would really appreciate if you can help to answer the question. Thanks a lot.
