My problem was caused by the file bb-settings.php (in the root folder of the forum) only being partially FTP-ed to the server. About 20 lines were missing from the end of it. I mentioned that it was that file in my previous post.

It seems unlikely to me that you’d have exactly the same problem as it seems to have been an FTP issue to do with my computer or web host. You could check your bb-settings.php file though just to be sure. It should be 1219 lines long and the last line should read

bb_send_headers();
