Hello
When I start my LACIE I get allaways this message
Warning: session_start(): open(/tmp/sess_b4240370df377e99f4031c29b6acdabe, O_RDWR) failed: Read-only file system (30) in /usr/htdocs/home.hm on line 2 Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /usr/htdocs/home.hm:2) in /usr/htdocs/home.hm on line 2
Sometimes I can acess to my files via samba sometimes no
Sometimes I can open my web page sometimes not
What I can do to reinstall the software or correct the problem???
Thanks in advance
