I was putting together a post for IIP 5.0, listing all the features and explaining them somewhat and also including some notes regarding some various issues with speed and large sites and such. The one thing I didn't have filled in was the subject. When the page displayed "all fields" message and said hit the back button I didn't think to much of it but after hitting the back button it was only to find the entire post gone... *sigh* lol
Normally the text and whatnot should have been there but it wasnt. I just tried testing this on my test site with the standard templates and the body of the post was there when I hit the back button. I think it may be the templates? I dunno..
Edit Note: This was during a preview, not straight in.
