Fatal error: require_once(): Failed opening required ....inc/header.inc.php on line 159

in the the first step:

Warning: file_exists(): open_basedir restriction in effect.

File(/usr/local/bin/php) is not within the allowed path(s):

In the second step

Path to php binary : /usr/local/bin/php not found

ine the Third step

inc : Writable (I can change it) So I click on NEXT

in the step just after:

I have error:

Fatal error: require_once(): Failed opening required

'.........../htdocs/inc/version.inc.php'

(include_path='.:/usr/share/php') in /htdocs/website dot tld /inc/header.inc.php on line 159

I've read tips that talk about changing the root, but where or how?

Thanks
