Product description vanishing

[GamesWorld]

Hi everyone, a couple weeks ago I listed new items on my site, which all worked fine, but a couple days ago I started listing new items on my site, and after about 20 I noticed that even though the descriptions where coming up in the preview page, once listed they are blank on the live site

I've tryed Chrome, Firefox, safari and IE and its always the same

If I type a line of text it works, but 2+ lines or pasting a block of text makes it become blank

Has anyone else had this and know of a way of fixing it?
