That's a strange error. It doesn't seem to be related to forum software.
Have you tried pressing the "backspace" button to return to the previous page?

The back space was disabled when that happened.

Another point (sorry I am complaining... as u know, I like this forum and I want it to be as nice as possible...):

The point is; the option of deleting a post is gone. For example; I made a post which I realised was wrong, in the thread "TORFL". But I can't delete it!

Can we have "Preview" out, without doing to Advanced?

You can Delete your own posts. Click "Edit Post" (within 72 hours of making a post) and then you'll see the "delete" button.
But you can't delete your own threads.
