include_path don't work

I've installed a new machine with linux RedHat Enterprise and I'm working n a LAN. I've configured Apache + MySQL and PHP, all is correct, but when I'm using a site that I've maked some times ago, and that on line it's opetive, the server said me the follow error:

Warning: Failed opening 'charset.php' for inclusion (include_path='.:/php/includes:/usr/share/php') in /home/padrino/public_html/website/antichisaporisardi/admin/header_shop.php on line 4


The path isn't correct. I've tryed to change the path srint at the /etc/php.ini file, and I've tryed to disable it, all times change the answer, but every time I've the same problem: I can't use the "include" or the "require" istruction in my website. I think I must change some configuration in some file, but I can't understand who and how.

Tanks for your help

Placing a semicolon in front of line include_path line in php.ini, save it, and then try your script.

If all else fails, use the ini_set() function. ie: ini_set("include_path", get_ini("include_path) . ":/home/padrino/public_html/website/antichisaporisardi/admin/");

Best of luck,
