Fresh install issues

I am doing a fresh install of add-free dolphin on a private dedicated server ...   I goto mydomain.com/community/install/index.php i get this error everytime.

Fatal error: Call to undefined function mb_internal_encoding() in /home/swaggcom/public_html/community/install/index.php on line 541

what the hell does this mean?

Can anyone help me?

I am on a linux box.

Thanks,

Shadow

Didnt get you clear, after fresh install,have you tried just typing your domain www.yourdomain.com in url without the community/ install /index.php? or have you corrcted the permission for orca?

error: Call to undefined function mb_internal_encoding()

just mean one - that you haven`t  mbstring extension in your php, you should include it
