Error: Can't recover form data - PhpUriMs/0.1-pre3.4.3b

Can't recover form data

It is impossible to read the file var/cache/save_form/ which contains the data you posted. Maybe it is a bug but you probably resent the form while this file have been deleted.
You can be redirected to the page you request but without posting values.
