php - Cakephp Warning: is_dir() [function.is-dir]: open_basedir restriction in effect

I uploaded my cakephp site to my web hosting server using cPanel...

And I got a list of errors after I uploaded the site.

Warning: is_dir() [function.is-dir]: open_basedir restriction in effect.
File(/usr/php4/lib/php/cake/libs) is not within the allowed path(s):
(/home/sumykids:/usr/lib/php:/usr/php4/lib/php:/usr/local/lib/php:/usr/local/php4/lib/php:/tmp) in ...

Anyone knows how to solve it?

I try adding .htaccess

    RewriteEngine on    RewriteRule    ^$
app/webroot/    [L]    RewriteRule    (.*) app/webroot/$1 [L]   
php_value     include_path .

It doesn't work too...
