Problems with open_basedir

Hello, I'm having some difficulties with open_basedir. If I include the prefix /home/web25637/ in open_basedir shouldn't it include every directory within this? We're getting this error: Warning: file_exists() [function.file-exists]: open_basedir restriction in effect. File(/home/web25637/domains/abc.ssf.scout.se/public_html//components/com_sef/sef.php) is not within the allowed path(s): (/home/web25637/:/tmp/:/var/www/:/usr/local/lib/php/:/etc/virtual/:/var/uploads/:/var/squirrelmail) in /usr/home/web25637/domains/abc.ssf.scout.se/public_html/index.php on line 46 As you can se, the file is within the prefix which is listed in allowed paths. How could it be the case that we're experiencing open_basedir restriction here? Cheers, Patrik
