In shared hosting should Safe_Mode be On or Off and with it on should it mess with any thing? The term Safe_Mode sounds as if it would keep the server safer but does having this on mess with sites code? Will it make there sites stop moving. From what i read with Safe_Mode Off users can read the password file on linux systems so i would think it should be On..

Any in put would be great on this.

PHP "safe mode" isn't safe in the context of a multi-user system. Use a setuid wrapper (eg suexec) if you care about security.

Thanks cperciva.. :)

Although I think you'll find most hosts have save_mode enabled.

Personally I have it enabled for clients and disabled for my own sites as I use the shell_exec() function and to monitor server performance and uptime.

Enableing safe_mode will do nothing but break lots of scripts and cause headaches to your customers. It might be a nice feature for a free host or a large ISP, but not a specialized Unix hosting company.

At least that's how I feel. :)
