>>>I've just tried to create a FAQ. I finished typing and wanted to save it in order to modify it later. At this moment there was a message: "A summary field should be at least 250 characters" and I was moved to FAQs page. I tried to go back, but this was a blank page instead. I tried few times to go back and forth, but the page was gone :(

>>>Of course, I'll re-type it, but it's quite inconvenient and I lost all my work. Do we really need to have this strict condition about Summary and can we at least have some warning about it?

>>If you have discovered a bug, just send it to me.

>I had the same thing few weeks ago, but it worked fine. I pressed the backspace, got to the previous page with all the text still there, added a few sentences from the other wndow where I had the full text, and that's it.

The ability for the browser to display or not the value entered in the previous page is somewhat difficult to understand. It seems for specific configuration that after a certain number of seconds that it will go away.
